An aeroplane is flying horizontally with a velocity of 216 km / hr 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

Heyy user ur answer.....

When the bomb is dropped, it will have an initial horizontal velocity which is equal to the speed of the aeroplane. So the bomb fall and travel forward too.
initial horizontal velocity, = 216 km/h=216×5/18=60 m/s
initial vertical velocity, = 0height, h = 1960mtime taken to fall = t
h=ut+1/2×gt^2........................g=9.8

1960=4.9t^2

t=√400=20sec

so, AB=ux×t=60×20=1200m

..i hope it will help [email protected]
