A body of mass m moving with a velocity v strikes a statioinalry body of mass m and sticks to it. What is the speed of the system?

A body of mass m moving with velocity 3km//h collides with a body of mass 2m at rest. Now, the combined mass starts to move with a velocity

A body of mass m moving with velocity 3km//h collides with a body of mass 2m at rest. Now, the coalesced mass starts to move with a velocity

A body of mass m moving with velocity 3km//h collides with a body of mass 2m at rest. Now, the combined mass starts to move with a velocity
