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 = -16t 2 -16t + 96, It will take the balloon blank seconds to hit the ground.

Answer 1

It takes the water ballon 2 seconds to hit the ground

Answer 2

-16t²-16t+96 = 0.  use quadratic equation the roots are x= -3, and 2.  2 is the only answer that makes sense.  So it takes 2 seconds
