if a package is dropped from 80ft up at 160 km/hr what is it's range before hitting the ground?

Answer 1

80 ft.

Answer 2

I'm guessing that the 160 km/hr is in the horizontal direction. First, find out how long it takes the package to hit the ground. The formula is 1/2at^2 where a is the acceleration of gravity (32 m/s^2). So

(1/2)(32)t^2 = 80
t^2 = 5
t = sqrt(5)

Next, find out how far the package goes horizontally.

160 km/hr * sqrt(5) seconds * 1hr/3600 seconds

That is your final answer.

Answer 3

namenot's answer is good except for a typo. Acceleration of gravity is 32 ft/s^2, not 32 m/s^2. This didn't affect the answer - it's good.
