Alowly high diver pushes off horizontally with a speed of 2.82 m/s from the edge of a platform that is 10.0 m above the surface of the water.
(a) at what horizontal distance from the edge of the platform is the diver 0.897 s after pushing off?
(b) at what vertical distance above the surface of the water is the diver just then?
(c) at what horizontal distance from the edge of the platform does the diver strike the water?

Amerry-go-round of radius r, shown in the figure, is rotating at constant angular speed. the friction in its bearings is so small that it can be ignored. a sandbag of mass m is dropped onto the merry-go-round, at a position designated by r. the sandbag does not slip or roll upon contact with the merry-go-round. how would you rank the following different combinations of m and r on the basis of the angular speed of the merry-go-round after the sandbag "sticks" to the merry-go-round from largest to smallest. a) m = 10kg, r = 0.25r b) m = 20kg, r = 0.25r c) m = 10kg, r = 0.50r d) m = 10kg, r = 1.0r e) m = 15kg, r = 0.75r f) m = 40kg, r = 0.25r
