During softball practice, a softball pitcher throws a ball whose height can be modeled by the equation h = -16t^2 (<--squared) + 24t + 1, where h=height in feet and t = time in seconds. How long does it take for the ball to reach a height of 6 feet?

  • Math -

    just plug in the numbers:

    6 = -16t^2 + 24t + 1
    16t^2 - 24t + 5 = 0
    (4t-1)(4t-5) = 0

    t = 1/4 (ball rising)
    t = 5/4 (ball falling)
