On a frictionless, horizontal air table, puck A with a mass of 0.25 kg is moving to the right toward puck B with a mass of 0.35 kg, which is
initially at rest. After the collision, puck A has a velocity of 0.12 m/s
to the left, and puck B has a velocity of 0.65 m/s to the right. What
was the speed of puck A before the collision?
