(b) Determine how much kinetic energy is lost or gained by the two balls (i.e., both together) during the collision. Is this collision elastic (i.e., total kinetic energy is conserved), inelastic (i.e., kinetic energy of the system decreases) or super elastic (i.e., kinetic energy of the system increases)?

Two balls, one of mass m and one of mass 2m, approach from orthogonal
directions with identical speeds v and collide. After the collision, the more massive
ball moves with the same speed v but downward (orthogonal to its original
direction) and the less massive ball moves with speed U at an angle 0 with respect
to horizontal. Assume that no external forces act during the collision.
