A ball thrown horizontally at 27 m/s travels a horizontal distance of 51 m before hitting the ground. From what height was the ball thrown?

  • physics - ,

    Dx = Xo*Tf = 51 m.
    27*Tf = 51.
    Tf = 51 / 27 = 1.89 s. = Fall time.

    h = Yo*Tf + 0.5g*Tf^2.
    h = 0 + 4.9*(1.89)^3 = 17.50 m.
