Two balls A and B. are of the sme size but the mass of A is double that of B. they move along the sme line in opposite direction. A with velocity `2mu` and B with velocity `3mu` If their total kinetoc energy after collision is half their total kinetic energy before collision find the coefficient of restitution. Find also their velocities after collision.
