Homework Statement
An Alaskan rescue plane traveling 40 m/s drops a package of emergency rations from a height of 113 m to a stranded party of explorers.
G = 9.8 m/s^2
Where does the package strike the ground relative to the point directly below where is was released? Answer in units of m.
What is the horizontal component of the velocity just before it hits? Answer in units of m/s.
What is the vertical component of the velocity just before it hits? (Choose upwards as the positive vertical direction) Answer in units of m/s.
Homework Equations
Square root of 2h/g = time of free fall
y = Voy(t) - 1/2gt^2
x = Vox(t) + Xo
The Attempt at a Solution
I solved the first part using 40 m/s x (square root of 2h/g) = 192.09 m
The answer to the second part was 40 because that is the constant horizontal component.
For the third part, I tried solving for T using x = Vox(t) + Xo and plugging that into y = Voy(t) - 1/2gt^2 but could not come up with the correct answer. I believe I need to include the time it takes to hit the ground somehow but do not know.
Any help is appreciated.
Thanks,
Ben
