!!!!!!!!!please type the answer rather than taking a picture!!!!!!!!!!

1. The sketch shows a ball rolling at constant velocity along a level floor. The ball rolls from the first position shown to the second in 1 second. The two positions are 1 meter apart. Sketch the ball at successive 1-second intervals all the way to the wall (neglect resistance). im a. Did you draw successive ball positions evenly spaced, farther apart, or closer together? Why? b. The ball reaches the wall with a speed of m/s and takes a time of fseconds.

Explanation / Answer

a) evenly spaced.

because the ball moving with constant velocity. so it covers equal distances in equal intervals of time

b) for 1 m distance time = 1sec

velocity = displacement / time = 1/1 = 1 m/sec

and total time = distance / time = 5 /1 = 5sec

the ball reaches the wall with a speed of 1 m/sec and takes a time of 5 sec
