What is the speed of the composite body

Reference no: EM13553922

Two cars of equal mass collide on a horizontal frictionless surface. Before the collision, car A is at rest while car B has a constant velocity of 6m/s. After the collision, the bodies are stuck together. What is the speed of the composite body (AB) after the collision? What are kinetic energies before and after the collision?
