Question

The greatest height to which a man can throw a stone is h. The greatest distance to which he can throw it, will be

• A. $\frac{h}{2}$
• B. $h$
• C. $2h$
• D. $3h$

Answer 1

The correct option is C

$2h$

For greatest height $\theta ={90}^{\circ }$
$H_{max}=\frac{u^{2}si{n}^2\left({90}^{\circ }\right)}{2g}=\frac{u^2}{2g}=h\left(given\right)$
$R_{max}=\frac{u^{2}si{n}^{2}2\left({45}^{\circ }\right)}{g}=\frac{u^2}{g}=2h$
