On a frictionless horizontal air table, puck A (with m 0.251 kg) is moving toward puck B (with m 0.371 kg), which is initially at rest. After the collision, puck A has velocity 0.125 m/s to the left, and puck B has velocity 0.655 m/s to the right.What was the speed v_Ai of puck A before the collision?
