Tanya kicks a ball into the air. The function that models this scenario is f (t) = - 16t2 + 96t, where h is the height of the ball in feet and t is the time seconds.

When will the ball hit the ground?

I guess the function is h (t) = - 16t^2 + 96t (instead of f (t))

When the ball hits the groung h (t) = 0

Then solve the equation for t

- 16t^2 + 96 t = 0

Divide by - 16

t^2 - 6t = 0

t (t-6) = 0

t = 0 is when the ball is kicked off

t = 6 is the answer.
