1. A pushing force of 12 N is applied on a box for 32 ms. What is the magnitude of the impulse of this force?
2. A game of pocket billiards begins when the white ball, called the cue ball, is rolled toward a set of 15 numbered balls arranged in a triangle. Let the set of 16 balls in the game represent a system, and let equal the momentum of the cue ball. What is the momentum of the system just after the cue ball strikes the numbered balls? Assume that friction and other nonconservative forces are negligible.
