- In an elastic collision of two particles with masses m1 and m2, the initial velocities are u1 and u2 = u1. If the initial kinetic energies of the two particles are equal, find the conditions on u1/u2 and m1/m2 such that m1 is at rest after the collision.

The velocity of particle A before the collision was 5 m/s and the velocity of particle B before the collision was 2.2 m/s.
