A cricketer can throw a ball to a maximum horizontal distance of $100\, m .$ The speed with which he throws the ball is (to the nearest integer) (in $ms ^{-1}$)

A

$30$

B

$42$

C

$32$

D

$35$

Solution

The formula for maximum range is given as,

$R_{\max }=\frac{u^{2}}{g}$

$100=\frac{u^{2}}{10}$

$u=10 \sqrt{10} m / s =32 m / s$
