(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.

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by  mathematical calculations  before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of  uranus  led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to   spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.
