On a frictionless horizontal table, puck A of mass 0.249 kg moves towards the puck B of mass 0.371 kg, which is initially at rest. After collision puck A has a velocity of 0.123 m/s to the left and puck B has a velocity of 0.646 m/s to the right. 

What was the speed of puck A before the collision? Also, find the change in the total kinetic energy of the system that occurs during the collision?

On a frictionless horizontal air table, puck A (with mass 0.249kg ) is moving toward puck B (with mass 0.371kg ), which is initially at rest. After the collision, puck A has velocity 0.123m/s to the left, and puck B has velocity 0.646m/s to the right. A)What was the speed V of puck A before the collision. B)Calculate , the change in the total kinetic energy of the system that occurs during the collision.
