Problem
An air-hockey puck of mass 0.50kg slides across a nearly frictionless table at 3.0ms−1 toward an identical puck of mass 1.5kg that is initially at rest. The pucks stick together on impact and move as one object.
(a) Calculate the magnitude and direction of the velocity of the combined pucks immediately after the collision.
(b) Determine the percentage of the original kinetic energy that is converted to non-mechanical forms during the collision.
