A ball of mass 1kg moving with a velocity of 15m`//`s undergoes a head on elastic collision with another ball of unknown mass at rest, and rebound with a velocity of `10m//s`. What is the mass of the other ball?

A ball of mass m moving with a velocity v undergoes an oblique elastic collision with another ball of the same mass m but at rest. After the collision if the two balls move with the same speeds , the angle between their directions of motion will be:
