A 20 g bullet moving directly upward at 850 m/s strikes and passes through the center of mass of a 7.0 kg block initially at rest. The bullet emerges from the block moving directly upward at 200 m/s.
1. To what maximum height, h, does the block then rise above its initial position?
2. If instead, the bullet strikes the block off-center, to what maximum height does the block then rise above its initial position?
3. Will the bullet emerge from the other end of the block with a lower, higher, or equal speed compared to when it passed through the center of mass? Explain.
