A bomb is dropped from an aeroplane when it is at a height h directly above a target. If the aeroplane is moving horizontally at a speed v, the distance bywhich the bomb will miss the target is given by

The time taken by the bomb to hit the ground is given byh=0×t+12gt2 or (2h/g)=t2∴ t=(2h/g)Horizontal speed of aeroplane = Horizontal speed of bomb (= v)The distance by which the bomb will miss the target is given by= horizontal velocity , time=vt=v(2h/g)
