Determine the change in the total kinetic energy of system

Reference no: EM13664099

On a frictionless, horizontal air table, puck C (with mass 0.250 kilogram) is moving toward puck D (with mass 0.290 kilogram), which is initially at rest. After the collision, puck C has a velocity of 0.120 m/s to the left, and puck D has a velocity of 1.580 m/s to the right.

(a) Find the speed of puck C before the collision?

m/s

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