A projectile is fired from point A at the edge of a cliff, whose initial velocity components are v0x = 60.0m / s and v0y = 175m / s. The projectile rises and then falls into the sea at point P. The projectile flight time is 40.0s and it does not experience appreciable air resistance in flight. a) Make a diagram of the problem, b) Determine how far it falls, c) what is the height of the cliff? and d) at what angle was it shot?
The cliff divers of Acapulco push off horizontally from rock platforms about hhh = 31 mm above the water, but they must clear rocky outcrops at water level that extend out into the water LLL = 5.2 mm from the base of the cliff directly under their launch point (Figure 1).
What minimum pushoff speed is necessary to clear the rocks?
