A flight carrying food packets is flying at a height of 1960m from the ground. The speed of the flight is given.
Find the time taken for a food packet dropped at that instance to hit the ground.
:
Using the falling object equation, time (t) in seconds; height = 0 (ground)
-4.9t^2 + 1960 = 0
-4.9t^2 = -1960
t^2 = %28-1960%29%2F%28-4.9%29
t^2 = 400
t = sqrt%28400%29
t = 20 seconds
