What was the speed of puck before the collision

Reference no: EM13333512

On a frictionless, horizontal air table, puck A (with mass 0.250 kg) is moving toward puck B (with mass 0.370 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 0.560 m/s to the right.

(a) What was the speed of puck A before the collision?

m/s

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