Example of law of conservation of linear momentum |
| Answer» Two bodies of mass M and m are moving in opposite directions with the velocities v. If they collide and move together after the collision, we have to find the velocity of the system.Since there is no external force acting on the system of two bodies, momentum will be conserved.Initial momentum = Final momentum(Mv – mv) = (M+m)VFinalFrom this equation, we can easily find the final velocity of the system. | |
