An Inelastic collision conservers Momentum But Not energy

Consider a collision between two bodies of mass m1 and m2 initially moving at speeds v1 and v2 respectively. They stick together after they collide so that each is moving at the same velocity v after the collision.


If there are no external force then

Conservation of momentum
m1v1+m2v2=(m1+m2)v

Given that the amsses and initially velocities are known we can solve for v such that

v=m1v1+m2v2m1+m2
