Consider the head-on collision of two identical bowling balls, each with mass 5 kg?

Posted on 2015-09-26 08:48:00 in Physics by JING

Ball A with velocity = ‹ 5, 0, 0 › m/s strikes ball B, which was at rest. Then ball A stops and ball B moves with the same velocity that ball A had initially.

(a) Choose a system consisting only of ball A.
What is the momentum change of the system during the collision?
What is the momentum change of the surroundings?

(b) Choose a system consisting only of ball B.
What is the momentum change of the system during the collision?
What is the momentum change of the surroundings?

(c) Choose a system consisting of both balls.
What is the momentum change of the system during the collision?
What is the momentum change of the surroundings?
