t=√(2h/g)=√(2×490/9.8)=10 s R=150 ×10=1500 m

Q. An airplane is flying horizontally at a height of $490 m$ with a velocity of $150 m s^{- 1}$ . 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?

1000 m

1500 m

750 m

2000 m

$t = \frac{2 h}{g} = \frac{2 \times 490}{9.8} = 10 s$

$R = 150 \times 10 = 1500 m$
