o Case 2 – If m2 >> m1 then , v1 ’ » -v1 & v2 ’ » 0 The heavier mass is undisturbed while the lighter mass reverses its ve
Completely inelastic collision
( A ball of mass m1 with initial velocity v1 strikes a ball of mass m2 initially at rest and the two ball stick to each other after collision , in the same direction )
