A body of a mass m moving with speed v collides elastically head on with another body of mass m, initially at rest. Show that the moving body will come to a stop after collision.

A body of mass m moving with velocity v collides head on with another body of mass 2 m which is initially at rest. The ratio of K.E. of colliding body before and after collision will be

A body of mass M moves with velocity v and collides elasticity with another body of mass m(M gt gt m) at rest , then the velocity of the body of mass m is

A body of mass m/2 moving with velocity v_0 collides elastically with another mass of m/3 . Find % change in KE of first body

Given below are two statements : one is labelled as Assertion A and the other is labelled as Reason R. Assertion A : Body "P" having mass M moving with speed 'u" has head-on collision elastically with another body 'Q' having mass 'm' initially at rest. If Mgtgtm , body Q will have a maximum speed equal to "2u' after collision Reason R : During elastic collision, the momentum and kinetic energy are both conserved. In the light of the above statements, choose the most appropriate answer from the options given below:

A body of mass M moving with a speed u has a ‘head on’, perfectly elastic collision with a body of mass m initially at rest. If M > > m , the speed of the body of mass m after collision, will be nearly :

A body of mass m moving with velocity v makes a head-on collision with another body of mass 2 m which is initially at rest. The loss of kinetic energy of the colliding body (mass m ) is
