Q. An airplane is flying horizontally at a height of $490\, m$ with a velocity of $150 \,ms^{-1}$. A bag containing food is to be dropped to the jawans on the ground. How far from them should the bag be dropped so that it directly reaches them?

Motion in a Plane

Solution:

$t=\sqrt{\frac{2h}{g}}=\sqrt{\frac{2\times490}{9.8}}=10 s$
$R=150 \times10=1500\, m$
