A hockey puck with momentum 3.5 kg m/s is struck by a hockey stick.
The stick causes the direction of motion of the puck to reverse.
The stick exerts an average force of 1200 N during the impact with the puck. The stick and puck are in contact with each other for a time of 0.0050 s.
What is the magnitude of the momentum of the puck as it leaves the hockey stick?
