A lump of putty and a rubber ball have equal mass. Both are thrown with equal speed against a wall. The putty sticks to the wall. The ball bounces back at nearly the same speed with which it hit the wall. Which object experiences the greater momentum change? a) Not enough information is given to determine the answer. b) The ball experiences the greater momentum change. c) The putty experiences the greater momentum change. d) They both experience the same momentum change.
