JEE MAIN - Physics (2023 - 24th January Morning Shift - No. 14)

The maximum vertical height to which a man can throw a ball is 136 m. The maximum horizontal distance upto which he can throw the same ball is :
136 m
272 m
68 m
192 m

Explanation

For vertical throw,

$$ \begin{aligned} & h=\frac{v^{2}}{2 g} \\\\ & v=\sqrt{2 g h}=\sqrt{2 g \times 136} \quad...(1) \end{aligned} $$

For max range, $\theta=45^{\circ}$

$R_{\max }=\frac{v^{2}}{g} \quad...(2)$

From (1) and (2)

$$ \begin{aligned} R_{\max } & =\frac{v^{2}}{g}=\frac{2 g \times 136}{g} \\\\ & =272 \mathrm{~m} \end{aligned} $$
