(from tipler, problem 8-40 on p. 282). a wedge of mass m is placed on a frictionless horizontal surface, and a block of mass m is placed on the wedge, which also has a frictionless surface. the block’s center of mass moves downward a distance h as the block slides from its initial position to the horizontal floor. (a) what are the speeds of the block and of wedge as they separate from each other and go their own ways? (b) check the plausibility of your answer to (a) by considering the limiting case when m is much greater than m.
