m/s2. After 2 seconds he reaches a speed of 2.4 m/s. What is
his momentum at this point?
A. 359.3 kg.m/s
B. 105.6 kg.m/s
C. 211.2 kg-m/s
O D. 36.7 kg-m/s

Answers

The momentum of the cyclist and bicycle at this point is 211.2 kg·m/s, calculated by multiplying their combined mass (88 kg) by their velocity (2.4 m/s). The correct answer is C.

The momentum of an object is defined as the product of its mass and velocity. To find the momentum of the cyclist at this point, we can use the equation: momentum = mass × velocityFirst, let's find the mass of the cyclist and his bicycle. We are given that their combined mass is 88 kg. Next, we need to find the velocity of the cyclist. We are given that he reaches a speed of 2.4 m/s after 2 seconds, and that he accelerates at a rate of 1.2 m/s². We can use the equation of motion: velocity = initial velocity + acceleration × timeThe initial velocity is 0 m/s (since the cyclist starts from rest), the acceleration is 1.2 m/s², and the time is 2 seconds. Substituting these values into the equation, we get:
velocity = 0 + 1.2 × 2 = 2.4 m/sFinally, we can calculate the momentum by multiplying the mass and velocity:
momentum = 88 kg × 2.4 m/s = 211.2 kg·m/sTherefore, the correct answer is C. 211.2 kg·m/s.

I think the third one is the correct answer. If you look at the other graphs, the numbers do not match up with the information given. Hope this helps!

In a gym the students raced with each other and teacher is recording everyone's speed than the second graph is representing correctly.

What is a graph?

A graph is a visual depiction of statistical data or a logical relationship between variables. Graphs serve a predictive purpose because they have the virtue of displaying broad trends in the mathematical behavior of data. However, as just approximations, they may be incorrect and occasionally deceptive.

Most graphs have two axes, with the axis denoting a set of independent variables and the vertical axis denoting a set of dependent variables. The most typical graph is indeed a broken-line chart, where the regression coefficient is typically a factor of duration.

In the second graph the speed of every student is represented accurately, therefore the second graph is correct.

Answers

Answer:

Explanation:

the magnitude of a=(change in speed)/(the time took to accelerate to the speed above)

So for that sports car, a=(26.8m/s-0m/s)/(5.1s)=5.2549m/[tex]s^{2}[/tex], knowing from the question that the sig fig of this question depend on "5.1 seconds", so the answer should be 5.3 m/[tex]s^{2}[/tex]

If you force the magnitude of the vector to stay the same, but increase the vertical component value, what happens to the horizontal component of the vector?

Answers

Answer:

The horizontal component reduces

Explanation:

The magnitude of a vector is found by taking the root of the sum of the squares of the components of the vector

Therefore, when the values of one of the components is increased, while the other components of the vector stay the same, the magnitude of the vector increases

In order  to increase the value of one of the components of a vector and maintain the magnitude of the vector, the values of one or more of the other components must be reduced.

As such when the magnitude of the vector that has only a vertical and a horizontal component is forced to stay the same, and the vertical component is increased, the horizontal component must be reduced.

The increase in vertical component of the vector, causes a decrease in the horizontal component of the vector.

A vector can be represented in vertical and horizontal components.

[tex]V = V_x + V_y[/tex]

where;

[tex]V_x[/tex] is the horizontal component of the vector[tex]V_y[/tex] is the vertical component of the vector

[tex]V = Vsin(\theta) \ + Vcos(90-\theta)[/tex]

From the formula above, as one component vector increases, the other component reduces.

Thus, the increase in vertical component of the vector, causes a decrease in the horizontal component of the vector.

A closed system consists of a pendulum that is swinging back and forth. If
the pendulum's kinetic energy decreases, what else must happen to the
energy of the system?
a
A. Its gravitational potential energy must decrease.
B. Its total mechanical energy must increase.
O C. Its total mechanical energy must decrease.
O D. Its gravitational potential energy must increase.

Answers

Answer:

The correct choice is D. Its gravitational potential energy must increase

Explanation:

Conservation of Mechanical Energy

The total amount of mechanical energy, in a closed system in the absence of dissipative forces like friction or air resistance, remains constant.

This means that energy cannot disappear or appear and that potential energy can become kinetic energy or vice versa.

In a closed system like a pendulum, two types of energies are considered: Gravitational potential (U) and kinetic (K). Thus, the sum of both energies must remain constant in time.

Suppose the pendulum is at a state where U=150 J, and K=350 J. The total mechanical energy is:

M = 150 J + 350 J = 500 J

If the kinetic energy decreases to a new value, say K = 200 J, then the gravitational potential must increase to compensate for this new condition, that is: U = 300 J

The correct choice is D. Its gravitational potential energy must increase

Taking into account the definition of kinetic, potencial and mechanical energy, the correct answer is option D:  If  the pendulum's kinetic energy decreases Its gravitational potential energy must increase.

Kinetic energy

Kinetic energy is a form of energy. It is defined as the energy associated with bodies that are in motion and this energy depends on the mass and speed of the body.

Kinetic energy is defined as the amount of work necessary to accelerate a body of a given mass and at rest, until it reaches a given speed. Once this point is reached, the amount of accumulated kinetic energy will remain the same unless there is a change in speed or the body returns to its state of rest by applying a force.

Potential energy

On the other hand, potential energy is the energy that measures the ability of a system to perform work based on its position. In other words, this is the energy that a body has at a certain height above the ground.

Gravitational potential energy is the energy associated with the gravitational force. This will depend on the relative height of an object to some reference point, the mass, and the force of gravity.

Mechanical energy

Finally, mechanical energy is that which a body or a system obtains as a result of the speed of its movement or its specific position, and which is capable of producing mechanical work. Then:

Potential energy + kinetic energy = total mechanical energy

The principle of conservation of mechanical energy indicates that the mechanical energy of a body remains constant when all the forces acting on it are conservative (a force is conservative when the work it does on a body depends only on the initial and final points and not the path taken to get from one to the other.)

Therefore, if the potential energy decreases, the kinetic energy will increase. In the same way, if the kinetics decreases, the potential energy will increase.

This case

This principle can be applied in this case. The mechanical energy of the pendulum remains constant when all the forces acting on it are conservative.

So, the correct answer is option D:  If  the pendulum's kinetic energy decreases Its gravitational potential energy must increase.

Sarah is asked to sort out the list of ions and ionic compounds. How can Sarah differentiate between the ions and ionic compounds? Ions have a positive or negative charge, but an ionic compound's overall charge is zero. Ions have no charge, but ionic compounds have a positive charge. Ions have no charge, but ionic compounds have a negative charge. Ions have a positive or negative charge, but an ionic compound's overall charge is negative.

Answers

Answer:

Ions have a positive or negative charge, but an ionic compound's overall charge is zero.

Explanation:

Ionic compounds are compounds said to contain ions, which are atoms that have either lost electrons to be POSITIVELY CHARGED or gained electrons to be NEGATIVELY CHARGED. The negatively charged ions are called ANIONS while the positively charged ions are called CATIONS.

These cations (+ ions) and anions (- ions) make up ionic compounds in such a way that they give the ionic compound a net charge of ZERO. This is because the charges of the opposite ions that make up the ionic conpound are equal. For example, in the ionic compound CaCl2;

Ca is a cation with charge +2

Cl is an anion with charge -1, 2 atoms make a net charge of -2

When these two ions combine, they cancel out each other to form an ionic compound, CaCl2, with net charge 0 or neutral

Explanation:

Given that,

Initial speed = 20 m/s

Suppose, given time in charge are t= 0, 1, 2, 3, 4 sec

At t=0 sec,

We need to calculate the velocity and height

Using equation of motion

[tex]v=u-gt[/tex]

Put the value into the formula

[tex]v=20-9.8\times0[/tex]

[tex]v=20\ m/s[/tex]

Now, using second equation of motion

[tex]h=ut-\dfrac{1}{2}gt^2[/tex]

Put the value into the formula

[tex]h=20\times 0-\dfrac{1}{2}\times9.8\times0[/tex]

[tex]h=0\ m[/tex]

At t=1 sec,

We need to calculate the velocity and height

Using equation of motion

[tex]v=u-gt[/tex]

Put the value into the formula

[tex]v=20-9.8\times1[/tex]

[tex]v=10.2\ m/s[/tex]

Now, using second equation of motion

Put the value into the formula

[tex]h=20\times1-\dfrac{1}{2}\times9.8\times1^2[/tex]

[tex]h=15.1\ m[/tex]

At t=2 sec,

We need to calculate the velocity and height

Using equation of motion

[tex]v=u-gt[/tex]

Put the value into the formula

[tex]v=20-9.8\times2[/tex]

[tex]v=0.4\ m/s[/tex]

Student is attempting to hit a target 4 meters from the edge of the desk that is 1.4 m tall marble rules of a table horizontally as shown below according to the above information in diagram what velocity must a marble have to strike the target?

Answers

Answer:

The correct option is;

7.49 m/s

Explanation:

The time it takes the marble to fall vertically is given by the equation

s = u·t + 1/2·g·t²

Where;

s = The height of the table = 1.4 m

u = The initial vertical velocity = 0 (The marble is given only an initial horizontal push (velocity))

g = The acceleration due to gravity = 9.81 m/s²

t = The time it takes the marble to reach the ground 1.4 m below

Plugging in the values. gives;

1.4 = 0×t + 1/2 × 9.81 × t²

∴ t² = 1.4/(1/2 × 9.81) ≈ 0.28542 s²

t = √0.28542 ≈ 0.5342s

The horizontal range the marble is to cover in the approximately 1.87 seconds before it reaches the ground = 4 meters

Therefore, the velocity that allows the marble to reach 4 meters in 1.87 seconds is give as follows;

Velocity = Distance/Time = 4 m/(0.5342 s) ≈ 7.49 m/s

Therefore the horizontal velocity the marble must have to strike its target is approximately 7.49 m/s.
