In a slap shot in hockey, the stick and puck are only in contact for 0.030 s. During this time, the puck accelerates from rest to more than 100 mph! The mass of a hockey puck is about 160 g (a) A hockey puck is sitting stationary on a frozen pond. A player slaps the puck, accelerating it from rest to 45 m/s in 0.030 s. What is the average force on the hockey puck while it is in contact with the stick? (b) The hockey puck slides across the frozen pond until it comes to a stop. It has an initial speed of 45 m/s, but it slows down at a constant rate. After 1.0 s, its speed has dropped to 42 m/S. How far will the puck travel before it comes to rest?
