A cricketer can throw a ball to a maximum horizontal distance of $100 \,m$. With the same effort, he throws the ball vertically upwards. The maximum height attained by the ball is ......... $m$

A

$100$

B

$80 $

C

$60$

D

$50 $

Solution

(d) Maximum range $ = \frac{{{u^2}}}{g} = 100\,m$
Maximum height $ = \frac{{{u^2}}}{{2g}} = \frac{{100}}{2} = 50\,m$
