A bomb is dropped from a helicopter flying horizontal with a velocity of 720 km/h at an altitude of 980 m . After what time, the bomb will hit the ground ?

Text Solution

Verified by Experts

Given :
Velocity = 720 km/h
Altitude = 980 m
Formula : ` t = sqrt((2h)/(g)) = sqrt(( 2 xx 980)/(9 . 8 )) s`
`= 10 sqrt(2) s `
`= 14 . 14 s`
