Two bodies are projected from ground with equal speeds $20\ m/sec$ from the same position in same vertical plane to have equal range but at different angle above the horizontal. If one of the angle is $30{^\circ}$ the sum of their maximum heights is (assume $g = 10m/s^{2})$

(b) $H_{1} + H_{2} = \frac{u^{2}}{2g}(\sin^{2}{30{^\circ}} + \sin^{2}{60{^\circ}})$
$= \frac{20^{2}}{2 	imes 10}\left( \frac{1}{4} + \frac{3}{4} ight) = 20\ m$
