Part A On a frictionless, horizontal air table, puck A (with mass 0.150 kg) is moving toward puck B (with mass 0.400 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. What was the speed of puck A before the collision? Express your answer in meters per second. v = Submit Request Answer Part B ? m/s Calculate the change in the total kinetic energy of the system that occurs during the collision. Express your answer in joules. AK = Submit Request Answer ?
