Alan hits a hockey pick of mass 0.3 kg across a hockey rink with a velocity of 18 m/s to the east.
a. what is the momentum of the hockey puck?
b. if the puck was initially at rest and the time of impact was 0.25 seconds, what force did alan apply to the puck when he hit it?
c. the puck slides across the rink, losing 5 m/s of speed due to friction. what impulse is applied by friction?
d. when alan's puck is moving at 13 m/s east, it collides with a sticky foam block of mass 1.2 kg sitting on the rink. the puck sticks in the foam block and they move together. what was the momentum of the pick-block system before the collision?
e. what is the speed of the puck-block system after the collision?
