A fighter jet...

Question

A fighter jet plane is flying at a height of $500 m$ with a velocity $450 h^{- 1}$ . It releases a bomb when $500 m$ away from the enemy post. Will the bomb hit the post ? Take $g = 10 m s^{- 2}$ .

Open in App

Solution

$h = \frac{1}{2} g t^{2}$
$500 = \frac{1}{2} 10 t^{2}$
$t = 10 s e c s$
$v = 450 / 60 = 7.5 m / s$
$R = 7.5 \times 10 = 75 m$
it will not hit post
