Q. A body can throw a stone up to a maximum height of $10m$. The maximum horizontal distance that the boy can throw the same stone up to will be
A) $20\sqrt{2}m$
B) $10m$
C) $10\sqrt{2}m$
D) $20m$
Explanation
(d) $h_{\max} = \frac{u^{2}}{2g} = 10\ \ \ \ \ \lbrack\because\theta = 90^{o}\rbrack$
$u^{2} = 200$
$R_{\max} = \frac{u^{2}}{g} = 20m$
