On a frictionless, horizontal air table, puck A (with mass 0.245 kg ) is moving toward puck B (with mass 0.360 kg ), that is initially at rest. After the collision, puck A has a velocity of 0.122 m/s to the left, and puck B has velocity 0.660 m/s to the right.
I figured out the speed of Puck A before the collision to be .848 m/s
Now, I'm supposed to find the change in the total kinetic energy of the system that occurs during the collision.
How do I do this?

Only A has kinetic energy before the collision.
After the collision both a and B have kinetic energy so the change is Kinetic energy A before impact - (Kineitc energy of A after the impact plus kinetic energy of B after the impact)
