A ball traveling with some velocity v hits another ball elastically which is stationary. What will happen to the system?

A ball traveling with some velocity v hits another ball elastically which is stationary. What will happen to the system? Correct Answer The stationary ball will start moving with a velocity v and the moving ball will come at rest

In this case also we need to conserve the momentum and write the expression for e. After some calculation we will find that the stationary ball will start moving with a velocity v and the moving ball will come at rest.
