A 70.0 kg goalie at rest catches a 0.150 kg puck moving at 35.0 m/s. His recoil velocity is:
ASmall, opposite direction
BExactly zero, no motion
CSmall, same direction
DLarge, same direction
Answer & Solution
Correct answer: C. Small, same direction
1. Momentum of the puck is shared with the goalie.
2. The recoil is small and forward.
3. About 0.075 m/s.
