A hockey ball of mass 0.12 kg is moving at a speed of 25 m/s.
The ball hits a stationary hockey stick and bounces back at the same speed in the opposite direction.
The ball is in contact with the stick for 1.2 × 10-3 s.
Which of the following correctly identifies the magnitude of the change in momentum of the ball and the magnitude of the force applied to the ball?
Change of momentum = 3.0 kg m/s3.0 \text{ kg m/s}3.0 kg m/s; Force applied = 2500 N2500 \text{ N}2500 N
