Question

A ball of mass 1000g moving with 7m/s impinges another ball of twice its own mass
and moving with 1/6th of its own velocity and moves in the opposite direction. If the coefficient of restitution is 0.75, calculate the velocities of the two balls after impact.


Pl help me
Take a look at this example. It is very similar to yours.
