A 5.00 kg ball (ball 1), moving to the right at a velocity of +4.00 m/s on a frictionless table, collides headon with a stationary 7.60 kg ball (ball 2). Find the final velocities of the balls if the collision is as specified below.
(a) elastic collision
ball 1
ball 2
(b) completely inelastic collision
ball 1
ball 2
cant seem to figure out out how to get this started for each part in terms the correct formula to use, please help.

inelastic equation: only conservation of momentum can be used, I don't think you will solve it.
elastic equation; you can use both conservation of momentum and conservation of energy, you can solve it. A little algebra is required.
