Problem

A stone is projected vertically upward from the edge of a cliff

25\,\text{m}

high with an initial speed of

15\,\text{m}\,\text{s}^{-1}

. Assuming

g = 9.8\,\text{m}\,\text{s}^{-2}

and neglecting air resistance, determine the speed with which the stone strikes the ground at the base of the cliff.
