The equation is h (t) = - 16t2 + 1600.

When the package hits the ground, h (t) = 0: 0 = - 16t2 + 1600 To solve by factoring: 0 = - 16 (t2-100) 0 = - 16 (t+10) (t-10) t = - 10 and + 10 seconds.

Since we aren't interested in negative time, t = 10 seconds.

Hello there!

To answer this question you will jave to do the following steps:

Steps:

0 = - 16 (t2-100) 0

= - 16 (t+10) (t-10) t =

-10 and + 10 seconds.

So the answer would be:

Answer: t=10

or

t=10 sec

Hoping this helsp you!
