Answer:8730.63 m
Step-by-step explanation:
Given
Bomber velocity
relative to ground
Altitude of the bomber

Range of bomb when bomb when it is released is given by

where

Horizontal velocity of bomber is equal to bomb horizontal velocity
time taken by to cover 3580 m




Therefore range of bomb is

Therefore bomber must release the bomb at a horizontal distance of 8730.63 m before the hit point
