A 4.00 kg ball (ball 1), moving to the right at a velocity of +3.00 m/s on a frictionless table, collides head-on with a stationary 7.80 kg ball (ball 2). Find the final velocities of the balls if the collision is as specified below.
(a) elastic collision
ball 1
?? m/s
ball 2
?? m/s
(b) completely inelastic collision
ball 1
(I got this right with 1.02 m/s)
ball 2
(I got this right with 1.02 m/s)
I know part one has to do with conservation of KE, but whenever I try to work it, I get a wrong answer. Can someone help me?
