Coefficient of restitution and direct collisionsExam-style questions

The second equation every collision needs: Newton's law of restitution, speed of separation = e × speed of approach. With it you can say where two spheres go after a direct impact, which values of e reverse a direction, how much kinetic energy is lost, what impulse each sphere receives, how a sphere rebounds from a fixed wall, and whether the spheres will collide again.
