The cliff divers of Acapulco push off horizontally from rock platforms about 35 m above the water, but they must clear rocky outcrops at water level that extend out into the water 5.0 m from the base of the cliff directly under their launch point. See Fig. 3-53. What minimum pushoff speed is neces- sary to clear the rocks? How long are they in the air? 35 m |5.0 m| FIGURE 3-53 Problem 64.
