At the height 80 m , an aeroplane is moved with 150 m/s. A bomb is dropped from it so as to hit a target. At what distance from the target should the bomb be dropped? (given g=10 m/s2)

Question

At the height 80 m , an aeroplane is moved with 150 m/s. A bomb is dropped from it so as to hit a target. At what distance from the target should the bomb be dropped? (given g=10 m/s2) (A) 605.3 m (B) 600 m (C) 80 m (D) 230 m

Time taken by the bomb to reach the ground is given by

t = (\frac{2 h}{g})

t = (\frac{2 \times 80}{10}) = 4 sec

Horizontal velocity of bomb

= 150 m / s

Horizontal distance covered by bomb

= 150 \times 4 = 600 m

Hence, the bomb should be dropped

600 m

before the target.

Q. At the height 80m , an aeroplane is moved with 150m/s. A bomb is dropped from it so as to hit a target. At what distance from the target should the bomb be dropped? (given g=10m/s2)

605.3 m

600 m

80 m

230 m

Time taken by the bomb to reach the ground is given by t=(g2h​)​ t=(102×80​)​=4sec Horizontal velocity of bomb =150m/s Horizontal distance covered by bomb =150×4=600m Hence, the bomb should be dropped 600m before the target.

Q. At the height $80 m$ , an aeroplane is moved with $150 m / s$ . A bomb is dropped from it so as to hit a target. At what distance from the target should the bomb be dropped? (given $g = 10 m / s^{2}$ )

Time taken by the bomb to reach the ground is given by
$t = (\frac{2 h}{g})$
$t = (\frac{2 \times 80}{10}) = 4 sec$
Horizontal velocity of bomb $= 150 m / s$
Horizontal distance covered by bomb $= 150 \times 4 = 600 m$
Hence, the bomb should be dropped $600 m$ before the target.
