Consider a problem involving tow rubber balls. The upper ballhas half the mass of the lower ball. Both are dropped from the sameheight and so they arrive at thetable traveling downward at a givenspeed v0. Assume the lower ball bounces perfectly elastically offthe table, and is now moving upward at v0, then bouncesperfectlyelastically off the upper ball (which at that moment stillmoving downward at v0.) Find the final speed upward of the upperball immediately after the collisions. (Hint will begreater thenv0).

Side note: I tried this and got 3*v0. This is not the rightanswer.
