3. A 0.200 kg airtrack glider moving at 1.20 m/s bumps into a 0.600 kg glider at rest.
a.) Find the total kinetic energy after collision if the collision is elastic. .144J I got that one.
b.) Find the total kinetic energy after collision if the collision is completely inelastic.

a. yes.
b. on this solve the Velocityies after the collision by conservation of momentum. I don't see enough information to do it.
