On a frictionless horizontal air table, puck A (with mass 0.253 kg) is moving toward puck B (with mass 0.374 kg) which is initially at rest. After the collision, puck A has velocity 0.119 m/s to the left and puck B has velocity 0.649 m/s to the right. Part A: What was the speed vAi of puck A before the collision? Part B: Calculate ΔK, the change in the total kinetic energy of the system that occurs during the collision.
