On a frictionless horizontal air table, puck A (with mass 0.254 kg ) is moving toward puck B (with mass 0.369 kg ), which is initially at rest. After the collision, puck A has velocity 0.124 m/s to the left, and puck B has velocity 0.655 m/s to the right.

A)What was the speed vAi of puck A before the collision?

B)Calculate ΔK, the change in the total kinetic energy of the system that occurs during the collision.
