Part A A hockey player takes a slap shot at a puck at rest on the ice with a contact time of 0.0143 s. The puck glides over the ice for 6.31 ft with- out friction, at which point it runs over a concrete surface, where the puck decelerates at a uniform rate of 16.5 ft/s2. If the velocity of the puck is 48.2 ft/s after traveling 135 ft from the point of impact, what is the average acceleration imparted to the puck by the hockey stick? Answer in units of ft/s2. Part B How far does the puck travel from the point of contact with the hockey stick before stopping? Answer in units of ft. Part c What is the total time the puck is in motion, neglecting contact time? Answer in units of s,Find the magnitude of the displacement of a point on a wheel initially in contact with the ground when the wheel (of radius 53.7 cm) rolls forward half a revolution. Answer in units of cm.
