Best ResponseYou've already chosen the best response.0A collision is elastic or not depending on whether KE is conserved or not, as we've seen in a few of your questions now. That being the case, Conservation of Momentum is unchanged whether KE is conserved or not.

Best ResponseYou've already chosen the best response.0If a body of mass m has velocity v before an event and velocity v' after the event, then the change in KE is \[ KE_{after}  KE_{before} \] \[ = \frac{1}{2}mv'^2  \frac{1}{2}mv^2 \] \[ = \frac{1}{2}m (v'^2  v^2) \]
