An aeroplane is flying horizontally with a velocity of 600 km/h and at a height of 1960 m. When it is vertically above a point A on the ground a bomb is released from it. The bomb strikes the ground at point B. The distance AB is :

Options

A. 1200 m
B. `0.33 km `
C. `333.3 km`
D. 33 km

Answer

D

Explanation

`h = 1/2 g t ^(2) impliest = sqrt ((2 xx 1960)/(9.8)) = 20 s `
`therefore s = AB = ut = 600 xx (20)/( 60 xx 60)= 3.33 km`
