A 50.0-g Super Ball traveling at 30.0 m/s bounces off a brick wall and rebounds at 16.0 m/s. A high-speed camera records this event. If the ball is in contact with the wall for 4.60 ms, what is the magnitude of the average acceleration of the ball during this time interval?

Expert Answer

Step 1

Finding the magnitude of the average acceleration of the ball:

Given information:

The initial velocity of the ball is 30 m/s.

The rebound velocity of the ball is 16 m/s.

If the ball is in contact with the wall for 4.6 ms.

Convert millisecond to seconds.

Step 2

Formula used:

We use first equation of motion to find the magnitude of the average acceleration.

Rearrange the first equation of motion to find the average velocity.

Here, v is the final velocity, u is the initial velocity and t is the time taken.

Step 3

Calculation:

As, after rebounding ball changes its direction we take the direction of v opposite to u.

So, initial velocity...
