3/204 The ice-hockey puck with a mass of 0.20 kg has a velocity of 12 m/s before being struck by the hockey stick. After the impact the puck moves in the new direction shown with a velocity of 18 m/s. If the stick is in contact with the puck for 0.04 s, compute the magnitude of the average force F exerted by the stick on the puck during contact, and find the angle B made by F with the x-direction. 12 m/s 20% 18 m/s Problem 3/204
