Question

A Bomb Is Dropped From An Aeroplane Flying Horizontally With A Velocity Of 720Kmph At An Altitude Of 980M .Time Taken By The Bomb To Hit The Ground Is_____

Answer 1

Here is your answer

Explanation:

The bomb starts with vertical component of speed zero.

 

hence time to hit the ground is calculated using the equation, h = (1/2)g×t2  

 

980 = (1/2)×9.8×t2 ...........(1)

 

from eqn.1), we get t = 10√2 = 14.14 s
