Question- Consider the head-on collision of two bowling balls, each with mass 5 kg (see figure), Ball A with velocity v→ = <4, 0, 0> m/s strikes ball B, which was at rest. Then ball A stops and ball B moves with the same velocity v→ that ball A had initially.

Part A: Choose a system consisting only the ball A.
What is the momentum change of the system during the collision?
What is the momentum change of the surroundings?
Part B: Choose a system consisting only ball B.
What is the momentum change of the system during the collision?
What is the momentum change of the surroundings?
Part 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?
