On a frictionless, horizontal air table,puck A (with mass 0.250 kgkg ) ismoving toward puck B (with mass0.360 kgkg ), that is initially at rest. After thecollision, puck A has a velocity of0.119 m/sm/s to the left, andpuck B has velocity 0.655 m/sm/s tothe right.
What was the speed of puck A before thecollision?
Calculate the change in the total kinetic energy of the systemthat occurs during the collision.
