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?
