After a baseball is hit, the height h (in feet) of the ball above the ground t seconds after it is hit can be approximated by the equation h=-16t^2+70t+4. Determine how long it will take for the ball to hit the ground. Round your answer to two decimal places.

  • Algebra I -

    When it hits the ground, h=0
    solve for that time. It is a quadratic, use the quadratic equation.
