A body of mass `m` moving at a constant velocity `v` hits another body of the same mass moving with a velocity `v//2` but in the opposite direction and sticks to it. The common velocity 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 ball of mass M moving with a velocity v collides perfectly inelastically with another ball of same mass but moving with a velocity v in the opposite direction. After collision

A ball of mass m moving with a velocity collides head on elastically with another of the same mass m but moving with a - in the opposite direction). After the collision
