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 necessary to clear the rocks? How long are they in the air?
Step by step solution
Step 1 of 2</p>
The height of the cliff h = 35 m.
The distance of the rock from the base of the cliff (x) = 5 m.
Let v be the horizontal speed with which the jumpers jump the cliff. Considering the downward direction as the positive y direction and the origin at the point from which the divers jump off the cliff.
