Question
Consider the head-on collision of two identical bowling balls, each with mass 8 kg (see figure). Ball A with velocity = m/s strikes ball B, which was at rest. Then ball Astops and ball B moves with the same velocity that ball A had initially. Choose a system consisting only of ball A. What is the momentum change of the system during the collision? 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? 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?Explanation / Answer
a) 0-40 = -40
40-0 = 40
b) 40-0 = 40
0-40 = -40
c) 40-40=0
40-40=0
