If the initial velocity of a projectile be doubled, keeping the angle of projection same, the maximum height reached by it will

A

Remain the same

B

Be doubled

C

Be quadrupled

D

Be halved

Solution

(c) $H = \frac{{{u^2}{{\sin }^2}\theta }}{{2g}}\,$

$\therefore \,\,H \propto {u^2}.$

If initial velocity be doubled then maximum height reached by the projectile will quadrupled.
