He landed safelyon the far side of the river. It was reported that he leap 22 feetacross while falling 20 feet.-Representing the horizontal distance jumped as L and the verticaldrop as h , as shown in the figure, derive an expression for theminimum speed v he would need to make his leap if he ran straightoff the cliff?
