Elastic collision of a mass

A block of mass m = 2.32 kg slides down an alpha = 29.2° incline which is h = 3.56 m high. At the bottom, it strikes a block of mass M = 7.06 kg which is at rest on a horizontal surface (see drawing in attached Word document). If the collision is elastic, and friction can be ignored, determine the velocity of the smaller block after the collision. The smaller block is traveling in the positive direction when it hits the stationary block.
