A paintball is fired horizontally from a tower 45 m above the ground. If the paintball gun fires at 90 m/s… How long does it take for the paintball to hit the ground? How far away from the tower will the paintball land?

Answers

Answer:

The time taken for the paint ball to hit the ground is [tex]t = 2.143 \ s[/tex]

The distance of the landing point from the tower is [tex]d = 192.86 \ m[/tex]

Explanation:

From the question we are told that

   The height of the tower is [tex]h = 45 \ m[/tex]

    The speed of the paintball in the horizontal direction is  [tex]v_x = 90 \ m/s[/tex]

Generally from kinematic equation we have that

      [tex]h = ut + \frac{1}{2} at^2[/tex]

Here u is the initial  velocity of the paintball in the vertical direction and the value is 0 m/s , this because the ball was fired horizontally

         a is equivalent to [tex]g = 9.8\ m/s^2[/tex]

        t is the time taken for the paintball to hit the ground

   So    

       [tex]45 = 0* t + \frac{1}{2} 9.8 * t^2[/tex]

=>    [tex]t = 2.143 \ s[/tex]

Generally the distance of its landing position from the tower is

         [tex]d = v * t[/tex]

=>      [tex]d = 90 * 2.143[/tex]

=>    [tex]d = 192.86 \ m[/tex]

Carol pushes down at an angle of 30 degrees from the vertical on a 10.0 kg wood crate causing the crate to move across a wood floor at a constant velocity of 2.0 m/s. How much force does Carol exert on the crate? (μs = 0.5 and μk = 0.2)

Answers

Answer:

F = 39.2 N

Explanation:

Since, the object is in uniform motion. Therefore, the frictional force on object will be:

Frictional Force = μk N = μk mg

where,

μk = coefficient of kinetic friction = 0.2

m = mass of crate = 10 kg

g = 9.8 m/s²

Therefore,

Frictional Force = (0.2)(10 kg)(9.8 m/s²)

Frictional Force = 19.6 N

The horizontal component of force must be equal to this frictional force to continue the uniform motion:

F Sin 30° = 19.6 N

F = 19.6 N/Sin 30°

F = 39.2 N

A force of 5 N gives to mass my and an acceleration of 8m/s2 and a mass m2
an acceleration of 24m/s2. What acceleration would it give if both masses are
tied together

Answers

Answer:

a=6m/sec²

Explanation:

f=5 N

a1=8m/sec²

a2=24m/sec

m1=f/a1=5/8kg

m2=f/a2=5/24kg

New, f=(m1+m2)a

a=5/5/8+5/24=5/15+5/24=24*5/20

a=6m/sec²

The motion of a car on a position time graph is represented with a horizontal tine What does this indicate about the car's motion?

Answers

Answer:

Position-Time graphs display the motion of a object by showing the changes of velocity with respect to time.

The motion of a car on a position-time graph that is represented with a horizontal line indicates that the car has stopped moving.

A straight line with a positive slope indicates that the car is moving at a constant velocity, and thus the slope is constant. On the other hand, a curve with a changing slope, shows that the velocity is changing.

Which scenario describes an effect of tornadoes on the environment? a section of forest that has been burned a path through a town with uprooted trees a town near the coast with heavy flooding a sandy beach that shows signs of erosion

Answers

Answer:

B; a path through a town with uprooted trees

Explanation:

took the quiz and got it right on edge2020!

The effect of tornadoes on the environment is a path through a town with uprooted trees. This, option B is correct.

What are tornadoes?

It is the typical weather event that contains strong winds and leaves a path of destruction up to 50 miles long. It is also defined as the violently rotating column of air that touches the ground and is usually attached to a thunderstorm.

It is developed from a severe thunderstorm in warm, moist, and unstable air and extended up to 300 miles. The thunderstorms also generate heavy damage and devastate the environment in seconds and cause more fatalities.

A swirling, funnel-shaped, whirling wind is called a tornado and it is accompanied by hurricanes and storms. Strong tornadoes last for twenty minutes and the winds are between 200 mph to 300mph. The United States and Canada are mostly tornado-affecting countries.

The effect of tornadoes is a path through a town with uprooted trees and hence, the ideal solution is option B.

How should the student change the circuit to give negative values for current and
potential difference?

Answers

Answer:

changing the polarity or direction of the battery changes the sign of the voltage and the current

Explanation:

The sign of current and voltage are due to established conventions.

The way that a DC circuit with negative current values ​​is by changing the polarity of the power source or by inverting the battery, this creates that the electrons move in the opposite direction

Changing the battery also changes the direction of the power difference, since the potential from positive to negative, in most cases negative is assigned a potential of zero volts

In summary, changing the polarity or direction of the battery changes the sign of the voltage and the current

The car on a track begins at the 80-cm mark. The car moves in the negative direction at a speed of 5 cm/s. After three seconds, a. What distance has the car traveled? b. What is the displacement of the car? c. What is the car's new position on the track? Please hurry up

Answers

Answer:

a) The car travelled a distance of 15 centimeters.

b) The displacement of the car is -15 centimeters.

c) The new position of the car on the track is 65 centimeters.

Explanation:

a) From Mechanical Physics we know that the distance travelled is magnitude of the route covered by the vehicle. If this car travels in a straight line and at constant velocity, then we can calculate the distance traveled by the following expression:

[tex]\Delta s = v\cdot \Delta t[/tex] (Eq. 1)

Where:

[tex]v[/tex] - Speed of the car, measured in centimeters per second.

[tex]\Delta t[/tex] - Time, measured in seconds.

[tex]\Delta s[/tex] - Distance travelled by the car, measured in meters.

If we get that [tex]v = 5\,\frac{cm}{s}[/tex] and [tex]\Delta t = 3\,s[/tex], then the distance travelled by the car is:

[tex]\Delta s = \left(5\,\frac{cm}{s} \right)\cdot (3\,s)[/tex]

[tex]\Delta s = 15\,cm[/tex]

The car travelled a distance of 15 centimeters.

b) The displacement is the vectorial distance between final and initial position. Then, we find that initial and final positions of the car are, respectively:

Initial position:

[tex]s_{o} = 80\,cm[/tex]

Final position: ([tex]s_{o} = 80\,cm[/tex], [tex]\Delta s = 15\,cm[/tex])

[tex]s_{f} = s_{o} -\Delta s[/tex] (Eq. 1)

[tex]s_{f} = 80\,cm-15\,cm[/tex]

[tex]s_{f} = 65\,cm[/tex]

And the displacement of the car is: ([tex]s_{o} = 80\,cm[/tex], [tex]s_{f} = 65\,cm[/tex])

[tex]d = s_{f}-s_{o}[/tex] (Eq. 2)

[tex]d = 65\,cm-80\,cm[/tex]

[tex]d = -15\,cm[/tex]

The displacement of the car is -15 centimeters.

c) The position of the car is its location regarding a point of reference. From point b) we find that the new position of the car on the track is:

[tex]s_{f} = 65\,cm[/tex]

The new position of the car on the track is 65 centimeters.

Describe the importance that keystone species have in the environment. What would happen if these species disappeared? How would it affect the local ecosystems?

Answers

Answer:

See the answer below

Explanation:

The keystone species of an environment are those species of organisms that are highly influential to the functioning of the ecosystem without whom the ecosystem would be drastically affected, lose its structure, or cease to exist totally.

The influence of keystone species in an environment is disproportionately high when compared to their population in the environment. If keystone species disappeared from an environment, such an environment will find it difficult to perform ecosystem functions with an entirely different structure. In some cases, the ecosystem might cease to exist in its entirety because the species that hold it together are no longer present.

What is the net force required to accelerate a 1.1 kg box at a rate of 2.8
m/s??

Answers

Answer:

Fnet = 13.86N

Explanation:

Net force can be defined as the vector sum of all the forces acting on a body or an object i.e the sum of all forces acting simultaneously on a body or an object.

Mathematically, net force is given by the formula;

[tex] Fnet = Fapp + Fg[/tex]

Where;

Fnet is the net force Fapp is the applied forceFg is the force due to gravitation

Given the following data;

Mass = 1.1kg

Acceleration = 2.8m/s²

To find the applied force;

[tex] Fapp = ma[/tex]

Substituting into the equation, we have;

[tex] Fapp = 1.1 * 2.8[/tex]

Fapp = 3.08N

To find the gravitational force;

We know that acceleration due to gravity, g = 9.8m/s²

[tex] Fg = mg[/tex]

Substituting into the equation;

[tex] Fg = 1.1 * 9.8[/tex]

Fg = 10.78N

To find the net force;

[tex] Fnet = Fapp + Fg[/tex]

Substituting into the equation, we have;

[tex] Fnet = 3.08 + 10.78[/tex]

Fnet = 13.86N

Therefore, the net force required is 13.86N

A person lifts a package weighing 75 N. If she lifts it 1.2 m off the floor, what work has she done?

Answers

Answer:

The answer is 90 J

Explanation:

The work done by an object can be found by using the formula

workdone = force × distance

From the question we have

workdone = 75 × 1.2

We have the final answer as

90 J

Hope this helps you

Answer:

[tex]\boxed {\boxed {\sf 90 \ Joules}}[/tex]

Explanation:

Work can be found by multiplying the force by the distance.

[tex]W=f*d[/tex]

The force of the package is 75 newtons.

The distance the package is lifted off the ground is 1.2 meters.

[tex]f= 75 \ N \\d=1.2 \ m[/tex]

Substitute the values in and multiply.

[tex]W= 75 \ N *1.2 \ m[/tex]

[tex]W=90 \ N*m[/tex]

1 Newton meter (N*m) is equal to 1 Joule (J).

Therefore, our answer of 90 Newton meters is equal to 90 Joules.

[tex]W= 90 \ J[/tex]

The work done is 90 Joules.
