Q. If a person can throw a stone to maximum height of $h$ metre vertically, then the maximum distance through which it can be thrown horizontally by the same person is
A) $\frac{h}{2}$
B) $h$
C) $2h$
D) $3h$
Explanation
(c) $h = \frac{u^{2}}{2g} \Longrightarrow u^{2} = 2gh$
Maximum horizontal distance
$R_{\max} = \frac{u^{2}}{g}$
[image:4_image166.emf]
$R_{\max} = 2h$
