Question

An aeroplane is moving horizontally at
30 ms at a height of 1 km towards a target
on the ground which is intended to be
bombed. The velocity with which bomb
hits the target is :
(a) 100 ms-1
(c) 144.6-1
(6) 200-1
(d) 150-1​

Answer 1

Answer:

Given speed of aeroplane =150 m/s and height of the plane from the surface =80 m.

Now horizontal distance BC covered by the bomb =v

=150×4=600m

Now distance between the target and dropping point of the bomb AC=
