Question

A package is dropped from a hovering helicopter.

If it takes 15.0s before the package strikes the ground, how high above the ground was the package when it was released ignore air resistance

Answer 1

The height of the package when it was released was 1102.5 meters

Step-by-step explanation:

A package is dropped from a hovering helicopter

Dropped means the initial velocity of the package is zero

The package takes 15 seconds to strike the ground

Ignore the air resistance

We need to know the height of the package when it was released

`h=ut+(1)/(2)gt^(2)`, where h is the height of the package

from the ground, u is the initial velocity, g is the acceleration of gravity

and t is the time

u = 0 , t = 15 seconds , g = 9.8 m/s²

`h=(0)(15)+(1)/(2)(9.8)(15)^(2)`

`h=0+1102.5`

h = 1102.5 meters

The height of the package when it was released was 1102.5 meters
