Answer:
Explanation:
Given
balloon is ascending at the rate of
Balloon is at a height of
As the package is dropped from the balloon it must possess the same initial velocity as the balloon
using
where v=final velocity
u=initial velocity
a=acceleration
s=displacement
time taken is given by
substituting values
as we consider downward direction as positive
therefore time taken to reach the bottom is t=5.44 s
