Determine the speed of puck before the collision

Reference no: EM13491526

On a friction less horizontal air table, puck A w/ mass 0.250 kg is moving towards puck B w/ mass 0.350 kg that 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 B before the collision?

b.) Calculate the change in the total kinetic energy of the system that occurs during the collision.
