A hockey puck sliding on a frictionless surface strikes a box at rest. After the collision, the two objects stick together and move at some final speed. (i) Check the statement below (there is only one) which describes the change in momentum and energy of the puck during the collision: The puck loses all of its original momentum, but only loses some (not all) of its mechanical energy. The puck conserves its original momentum and mechanical energy. The puck loses some, but not all, of its original momentum and mechanical energy. The puck loses some, but not all, of its original momentum, but conserves its mechanical energy. The puck conserves its original momentum, and loses some, but not all, of its mechanical energy.
