Two gliders on an air track collide. Glider A has a mass of 0.269 kg and is moving in the +x direction with a speed of 1.07 m/s. Glider B has a mass of 0.330 kg and is moving in the -x direction with a speed of 0.675 m/s. a) What is the velocity of A and B if the collision is completely inelastic? Calculate the velocities of b) A and c) B if the collision is completely elastic.

Im stuck on solving for the veloctiy of A + B if it in inelastic. I understand how to do it if it is elastic, just not sure what to do when KE is transfered.
