Near the surface of the Earth a block of mass M is sliding down an incline with angle µ1 = 30degrees. Initially the block is at a height h = 2.0 m with a speed of 12 m/s. The block slides down the incline, across the level surface, and up an incline with angle µ2 = 45degrees. If all the surfaces are frictionless, what maximum height H will the block reach?
