Mechanical Engineering

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