On a frictionless, horizontal air table, puck A (with mass0.250 kg) is moving toward puck B (with mass 0.350 kg), which isinitially at rest. After the collision, puck A has a velocity of 0.120 m/sto the left, and puck B has a velocity of 0.650 m/s to the right. (a)What was the speed of puck A before the collision? (b) Calculate thechange in the total kinetic energy of the system that occurs during thecollision.

On a frictionless, horizontal air table, puck A (with mass
0.250 kg) is moving toward puck B (with mass 0.350 kg), which is
initially at rest. After the collision, puck A has a velocity of 0.120 m/s
to the left, and puck B has a velocity of 0.650 m/s to the right. (a)
What was the speed of puck A before the collision? (b) Calculate the
change in the total kinetic energy of the system that occurs during the
collision.
