Find the velocity of a ball traveling 5 meters for 20 seconds.
Formula:
Substitute:
Solution:

Answers

Answer 1

Answer:

The answer is

0.25 m/s

Explanation:

The velocity of w given body given the distance and time taken can be found by using the formula

[tex]velocity = \frac{distance}{time} \\ [/tex]

From the question

distance = 5 m

time = 20 s

The velocity of the ball is

[tex]velocity = \frac{5}{20} = \frac{1}{4} \\ [/tex]

We have the final answer as

0.25 m/s

Hope this helps you

Answer 2

Formula: v = d/t

v = velocity

d = distance

t = time

We are given the distance (5 meters) and the time (20 seconds). Solve with these given values.

v = 5/20

v = 1/4 m/s

Best of Luck!

Represent the following sentence as an algebraic expression, where "a number" is the
letter x. You do not need to simplify.
The product of 5 and the difference of 9 and a number.

Answers

Answer:

não sei.................

One fifth of the difference between a number and one is given to us in this line. This must be written as an algebraic expression. Now that this number is expressed as a letter x difference.

What algebraic expression number is the letter x?

Thus, a number that is 5 more than x is equal to x+5. As a result, “5 more than a number” is represented by the algebraic expression “x+5”. The right response is therefore “x+5”.

We don't know what the value of the variable x is, but it can have any value. Since it is a constant number that is utilized with the variable term and is clearly defined, 5 is referred to as the coefficient of x.

Therefore, It can be calculated as 1, divided by 5, multiplied by the entity that is present. For the response to the query is 1 multiplied by x, minus 1, multiplied by 5 divided by 1.

A bicycle is going 2.6 m/s when it speeds up to 15.4 m/s in 8 seconds. What is the acceleration?​

Answers

Answer:

acceleration is 1.6 m/s^2

Explanation:

This is a question involving Kinematics so we can use one of the kinematic equations.

Given info: Vi= 2.6 m/s. Vf= 15.4 m/s. T= 8s

We need to solve for acceleration

The best equation to use is (Vf = Vi + at) as it contains all the info we need to solve for acceleration.

Now substitute the values given into the equation.

Vf = Vi + at >> 15.4 = 2.6 + a8

Now solve for a by rearranging the equation.

15.4 -2.6= 8a >> 12.8=8a >> 12.8/8= 8a/8 >> 1.6 =a

NOTES:

Acceleration is the rate of increase of velocity

Vf is final velocity or velocity after acceleration/de-accaeleration occurs

Vi is intial velocity or velocity before acceleration or de-accaeleration occurs

Time is time it took for a certain motion to occur.

HELP. A river flows South with a speed of 8m/s. From the shore, you see a boat moving South with a speed of 10 m/s. From their frame of reference, how fast are the rowers moving?

Answers

Answer:

18 m/s

Explanation:

Given that,

Speed of river is 8 m/s due South

From the shore, you see a boat moving South with a speed of 10 m/s. Both boat and river are moving in same direction. The resultant velocity will add up.

v = 10 m/s + 8 m/s

v = 18 m/s

Hence, the rowers are moving with a speed of 18 m/s.

Which changes would result in a decrease in the gravitational force between two objects? Check all that apply.

increasing the distance between the objects

Answers

Answer:

- increasing the distance between the objects

- decreasing the mass of one of the objects

- decreasing the mass of both objects

Explanation:

Got it right on Edge 2020.

The gravitational force is decreased by increasing the distance between the objects or decreasing mass of one or both of the objects

According to Newton's law of Universal Gravitation;  The force of gravity is directly proportional to the product of the masses between two bodies and inversely proportional to the square of the distance between them.

F = Gm1m2/r^2

Where;

G = gravitational constantm1 and m2 are the masses of the objects r = distance separating the objects.F = gravitational force

We can see from the formula above, that the following will result in the decrease of the force between two objects;

increasing the distance between the objects decreasing the mass of one of the objects decreasing the mass of both objects

A car was traveling at a velocity of 8 m/s and then accelerated at a rate of 5 m/sr^2, reaching a velocity of 85 m/s. How far did the car travel at this acceleration rate?

Answers

Answer:

716.1 m

Explanation:

A car was travelling at a velocity of 8m/s

It accelerated at 5m/s^2

It finally reached a velocity of 85m/s

The distance can be calculated by applying the fourth equation of motion

V^2= U^2 +2as

V= 85m/s

U= 8m/s

a= 5m/s^2

85^2= 8^2 + 2(5)(s)

7225= 64 + 10s

7225-64= 10s

7161=10s

s= 7161/10

= 716.1 m

Hence the car travelled at a distance of 716.1 m

The gravitational force between two objects is 3600 N. What will be the gravitational force between the objects if the mass of each object is reduced to one third of its original mass
A. 400 N
B. 1200 N
C. 10,800 N
D. 32,400

Answers

Answer:

It will reduce by 9 times and become 400 N.

This question can be solved using the concepts of Newton's Law of Gravitation, and gravitational force.

The gravitational force between the two objects if the mass of each object is reduced to one-third of its original mass will be "A. 400 N".

According to Newton's Law of Gravitation the gravitational force between two objects is given as follows:

[tex]F = \frac{Gm_1m_2}{r^2}[/tex]---------- eqn (1)

where,

F = Gravitational force between objects = 3600 N

G = Universal gravitational constant

m₁ = mass of the first object

m₂ = mass of the second object

r = distance between the objects

Now, the masses have become one-third of the original value:

[tex]F'=\frac{G(\frac{m_1}{3})(\frac{m_2}{3})}{r^2}\\\\F' = \frac{1}{9}\frac{Gm_1m_2}{r^2}\\\\using\ eqn\ (1):\\\\F' = \frac{F}{9} = \frac{3600\ N}{9}\\\\[/tex]

F' = 400 N

Which example best represents balanced forces? an elevator stopped on the third floor a basketball shot into a hoop a sled sliding down a snowy hill a tow truck pulling a car out of a ditch

Answers

Answer:

an elevator stopping on the third floor

Explanation:

The example that best represent balanced force as regards this question is an elevator stopped on the third floor.

Balanced force can be regarded as resultant force that has a magnitude of zero when acted on an object. When forces that are been subjected on a body are zero then the force is balanced.In the case of the elevator, immediately it stopped at a particular floor, then it will gave a balanced force, because at that point all forces acting on it becomes zeroWhen a car is pushed from a ditch , the force is acting from a side so its not balanced

Examples of balanced forces are;

The weight of object as well as normal force acting on it can be regarded as been balanced.When pushing a car at both opposite sides with the same forces.A lizard that hangs in vertical position.

Therefore option A is correct, because balanced force exist as the elevator stopped.

To cross the crevasse, the climber gets a running start and jumps in the horizontal direction. (A) What is the minimum speed needed by the climber to safely cross the gap? (B) What is the climber's velocity right before landing?​

Answers

Answer:

A) 5.5 m/s

B) 9.2 m/s

Explanation:

A) Given in the y direction:

Δy = 2.75 m

v₀ = 0 m/s

a = 9.8 m/s²

Find: t

Δy = v₀ t + ½ at²

2.75 m = (0 m/s) t + ½ (9.8 m/s²) t²

t ≈ 0.75 s

Given in the x direction:

Δx = 4.1 m

a = 0 m/s²

t = 0.75 s

Find: v₀

Δx = v₀ t + ½ at²

4.1 m = v₀ (0.75 s) + ½ (0 m/s²) (.75 s)²

v₀ ≈ 5.5 m/s

B) Find vᵧ.

v² = v₀² + 2aΔy

vᵧ² = (0 m/s)² + 2 (9.8 m/s²) (2.75 m)

vᵧ ≈ 7.34 m/s

Find v.

v² = vₓ² + vᵧ²

v² = (5.5 m/s)² + (7.34 m/s)²

v ≈ 9.2 m/s

How long should a spring be stretched for it to store 45 J of energy? The force constant of the spring is
540N/m?

Answers

Answer:

x = 0.4 m

Explanation:

When a spring is stretched from its equilibrium position. Some energy is stored in the spring. This energy is called the elastic potential energy of the spring. The formula used to calculate the magnitude of this stored energy is given as follows:

P.E = (1/2)kx²

where,

P.E = Elastic Potential Energy Stored in the spring = 45 J

k = Spring Constant = 540 N/m

x = amount of stretching = ?

Therefore,

45 J = (1/2)(540 N/m)x²

x² = (45 J)(2)/(540 N/m)

x = √(0.167 m²)

x = 0.4 m
