In the above question, if another body is at rest, then velocity of the compound body after collision is

A body of mass m moving with a constant velocity v hits another body of the same mass moving with the same velocity v but in the opposite direction and sticks to it. The velocity of the compound body after collision is

A body of mass m moving with a constant velocity v hits another body of the same mass moving with the same velocity v but in the opposite direction and sticks to it. The velocity of the compound body after collision is

A body of mass m, moving with the some velocity v collides with another body of same mass moving with same speed but in the opposite direction, sticks to it. The velocity of the compound body after collision is :

A body of mass 10 kg moving with a velocity of 5 ms^(-1) hits a body of 1 gm at rest. The velocity of the second body after collision. Assuming it to be perfectly elastic is

A body of mass m_(1) collides elastically with another body of mass m_(2) at rest. If the velocity of m_(1) after collision is (2)/(3) times its initial velocity, the ratio of their masses is :

A body of mass m_(1) collides elastically with another body of mass m_(2) at rest. If the velocity of m_(1) after collision is (2)/(3) times its initial velocity, the ratio of their masses is :
