A hockey player takes a slap shot at a puck at rest on the ice. The time of contact is 0.0146 s. The puck glides over the ice for 12.8 ft w/o friction, at which point it runs over a concrete surface. The puck then decelerates at 11.1 ft/s^2. If the velocity of the puck is 38 ft/s after traveling 84.6 ft, what is the average acceleration of the puck.
Part 2. How far does the puck travel before stopping.
Part 3. What is the total time the puck is in motion, neglecting contact time?
