A baseball is thrown up in the air from a height of 3 feet with an initial velocity of 23 feet per second. When does the baseball hit the ground?

  • Math -

    hf=hi+vi*t-16t^2
    0=3+23*t-16t^2

    this is a quadratic, solve it with the quadratic equation. I find it odd that Old English units (feet) are being used here, you must have a very old text, or a very old teacher.
