Question

a bomb is dropped from an aeroplane in level flight at 40m per sec at height of 490m above the ground how far ahead of the point of dropping does the bomb hit the ground use g:9.8 m per sec sq

Answer 1

first work in the vertical direction.
THe bomb falls under uniform acceleration g

initial height = 490m. Final height = 0
initial velocity = 0

Calculate thte time taken to fall to ground


THEN using that time, work in th horizontal direction.

Uniform speed (= plane speed) time = time from first bit

Calculate distance for uniform speed and time...

Answer 2

Can u please show the calculation

Answer 3

the first equation is s=ut+0.5at^2

the second is s=ut
