A horizontal spring, with a force constant of 39 N/m, is compressed 12.4 cm, and placed between a wall and a 0.17-kg box resting on a smooth floor. If the spring is released, the maximum speed of the box is a. 1.9 m/s d. 5.3 m/s b. 2.7 m/s e. 28 m/s c. 3.5 m/s 9. A moving curling stone, A, collides head on with a stationary stone, B. Both stones are of identical mass. If friction is negligible during this linear elastic collision, a. stone A will slow down b. after the collision, the momentum of stone B will be less than that of stone A c. both stones will come to rest shortly after the collision d. after the collision, the kinetic energy of the stone B will be less than that of stone A e. after the collision, stone A will have a speed of zero
