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. 3-57. What
minimum pushoff speed is necessary to clear the rocks? How long are they in the
air?
