vb=CRma(ua-ub)+maua+mbubma+mb
(CR)Coefficient of resitution
(ma)Mass of the first object
(mb)Mass of the second object
(ua)Initial velocity of the first object before impact
(ub)Initial velocity of the first object before impact

The Final Velocity of an Inelastic collision is a collision in which kinetic energy is not conserved due to the action of internal friction. The final velocity of the second object after impact is found using the following formula: va=CRma(ub-ua)+maua+mbubma+mb, where:

  • ua = initial velocity of the first object before impact
  • ub = initial velocity of the second object before impact
  • ma = mass of the first object
  • mb = mass of the second object
  • CR = coefficient of restitution
