A block of mass m = 2.26 kg slides down an α = 32.8 ° incline which is h = 3.54 m high. At the bottom, it strikes a block of mass M = 7.22 kg which is at rest on a horizontal surface, as seen in figure below. (Assume a smooth transition at the bottom of the incline.) If the collision is elastic, and friction can be ignored, determine the speed of the smaller block after the collision.
