Question 327219: How high was an object if it took 5 seconds to hit the ground after being dropped? h= -16t^2+s
With the help of solver91311 and the way the equation should look to solve it:
-16(5)^2 + s = 0
I got an answer of 400 feet.

You can put this solution on YOUR website!
s(t) = -16t^2 + h
s(5) = 0 ft.
-----------------------
-16(5)^2 + h = 0
h = 16(25)
height = 400 ft
