Question

Ball A is rolled in a straight line with a speed of 5

ms–1 towards a bigger ball B lying 20 m away.

After collision with ball B, ball a retraces'the path

and reaches its starting point with a speed of

4 ms–1. What is the average velocity of ball A

during the time interval 0 to 6s?​

Answer 1

Answer:0

Explanation:

As no net displacement is there because it reaches to its initial position after collision, the velocity will also be 0.
