Question 1166887: A golf is hit from the ground, and its height in feet above the ground is modeled by the function: h(t) = -16t2 + 180t. Where t is the time in seconds after the ball is hit.
When does the ball hit the ground?

.

at t = 180%2F16 = 11.25 seconds,


when  h(t) = 0 = -16t^2 + 180t = t*(-16t + 180).

Solved and answered.
