At the height 80 m , an aeroplane is moving 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`)

Options

A. 605.3 m
B. 600 m
C. 80m
D. 230 m

Answer

A

Explanation

The horizontal distance covered by bomb.
`BC = v_(H) xx sqrt((2h)/(g)) = 150 sqrt((2 xx 80)/(10)) = 600 m`

`:.` The distance of target from dropping point of bomb,
`AC = sqrt((AB)^(2)+(BC)^(2)) = sqrt((80)^(2)+(600)^(2)) = 605.3 m`
