the jet has a speed of 250 miles/hr, carried a bomb of 20 kgs, im 3000 ft. how seconds the bomb fall in to 3000 ft?
I suppose you have to find time for the bomb to strike the ground.
h = (1/2)*g*t^2
h = 3000ft
g = 32 ft/s^2
find out t
The data - jet's horizontal velocity and mass of the bomb - is irrelevant for the above computation of time
