3. A rescue plane drops a package to a stranded party of explorers. The plane is traveling horizontally at a velocity of
100.0 m/s at a height of 50.0 m above the ground.
a. How long will it take for the package to hit the ground?

Hi there!

For this part, we can disregard the horizontal velocity because horizontal and vertical motion are INDEPENDENT.

We can used the simplified equation to solve for time:

[tex]t = \sqrt{\frac{2h}{g}}[/tex]

Where:

h = height

g = acceleration due to gravity (assume g = 10 m/s²)

Plug in given values:

[tex]t = \sqrt{\frac{2(50)}{10}} = \sqrt{10}[/tex]

t ≈3.162 sec
