Question

An object of mass M moving with a velocity V,makes a head on elastic collision with a body of mass m,initally at rest.After the collision,the velocity of the object of mass M,along its original direction,equals v/n.obtain an expression for the ratio m/M​

Answer 1

The two objects M is moving with velocity V. It makes a head on elastic collision with a body of mass m which is initially at rest. After the collision, the velocity of object of mass M, along its original direction is equal to V/n. In elastic collision, the total momentum remains conserved.
