U. a hockey player takes a slap shot at a puck at rest on
the ice. the puck glides over the ice for 10 ft without
friction, at which point it runs over rough ice. the
puck then accelerates opposite its motion at a uniform
rate of - 20 ft/s2. if the velocity of the puck is 40 ft/s
after traveling 100 ft from the point of impact,
(a) what is the average acceleration imparted to the
puck as it is struck by the hockey stick? (assume that
the time of contact is 0.01 s.) (b) how far in all does
the puck travel before coming to rest? (c) what is the total time the puck is in motion, neglecting contact time?
