A stone of mass 200g is projected vertically upward with an initial speed of 25ms−1.
(i) Derive an expression for the maximum height reached by any body thrown vertically upward in terms of its initial speed u and the acceleration due to gravity g. No numerical values need be substituted in this part.
(ii) Using the result obtained in part (i), calculate the maximum height reached by the stone. Take g=9.8ms−2.
