Ablock of mass 0.2 kg, initially moving with a velocity of 10 m/s, slides up a curved ramp to a stop 10 m above its original level. a) draw free body diagrams of the block at the original level and also on the ramp. b) explain why the block stops moving at 10 m?

A12-g wad of sticky clay is hurled horizontally at a 100-g wooden block initially at rest on a horizontal surface. the clay sticks to the block. after impact, the block slides 7.5 m before coming to rest. if the coefficient of friction between the block and the surface is 0.65, what was the speed of the clay immediately before the impact?
