Question

On a frictionless horizontal air table, puck A (with mass 0.253 kg) is moving toward puck B (with mass 0.375 kg), which is initially at rest. After the collision, puck A has velocity 0.120 m/s the left,
and puck B has velocity 0.652 m/s to the right.
What was the speed vAi of puck A before the collision?
Calculate AK, the change in the total kinetic energy of the system that occurs during the collision.
