Question

A water balloon is thrown out of a window 96 feet above the ground. The balloon is traveling downward at 16 feet per second initially. If h is the balloon’s height in feet after t seconds, then

h = -16t2 -16t + 96,

It will take the balloon ________________ seconds to hit the ground.

Answer 1

I believe the answer is 6 seconds, but I didn't go by your equation. I just did 96/16 which is 6. The reason I did that is because it is traveling down at 16ft per second and it will stop after reaching 96 feet. 16ftps = 96 then divide 16 from each side to get 6.

Answer 2

The correct answer is two seconds.
