A 5.00 kg ball (ball 1), moving to the right at a velocity of +4.00 m/s on a frictionless table, collides head-on 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
(b) completely inelastic collision
cant seem to figure out out how to get this started for each part in terms the correct formula to use, please help.
physics 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.
