On a frictionless, horizontal air table, puck A (with mass 0.250 ) is moving toward puck B (with mass 0.350 ), which is initially at rest. After the collision, puck A has a velocity of 0.150 m/s to the left, and puck B has a velocity of 0.610 m/s to the right.
Calculate the change in the total kinetic energy of the system that occurs during the collision.
____ J
