A ball is thrown into the air with an upward velocity of 35 ft/s. Its height, h, in feet after t seconds is given by the function h(t) = -16t2 + 35t + 5.5. When will the ball reach a height of 13.25 feet?

Substitute h(t) with the number 13.25
So we have 13.25=-16t2+35t+5.5
Using the quadratic formula we have the ball will reach after 0.398 second or after 1.790 seconds
