Two projectiles are thrown with the same initial velocity at angles a and (900–a) with the horizontal. The maximum heights attained by them are h1 and h2 respectively. Then h1h2\frac{h_{1}}{h_{2}} is equal to –

A

sin2a

B

cos2 a

C

tan2 a

D

1

Answer

tan2 a

Explanation

Solution

h1 h2\frac { \mathrm { h } _ { 1 } } { \mathrm {~h} _ { 2 } } = tan2 a
