Particle A (mA = 1 kg) is given initial velocity 10 m/s to the right, while particle B (mB = 1:5 kg) is initially at rest. The coecient of restitution for any impact between A and B is 2/3 while the coecient of restitution for impact of either particle with either wall is 5/6. The particles slide along a smooth horizontal supporting surface. Compute the percentage of the kinetic energy remaining in the system of A and B at the moment just before A impacts the wall on the left for the rst time. (Consider the system to have 100% of its energy at the start.) Neglect all friction.
