A golf ball is hit from ground level. Its path is modelled by the relation h(t) = -4.9 t2 + 27.2t , where h is the ball’s height above the ground, in meters, and t is the time, in seconds. Determine the time the ball is in the air.
Well its in the air any time marked on the parabola but assuming that time is the difference between the two x intercepts it would be 5.551 seconds. (Sorry im not 100 percent sure what it means)
