    A dropped stone falls past a window, determine it's initial height

    Homework Statement A falling stone takes 0.33 s to travel past a window 2.2 m tall. From what height above the top of the window did the stone fall? Express your answer using two significant figures. Homework Equations Kinematic Equations ~ X= Vi (time) + .5gt^2 Vf^2 = Vi^2 + 2gxThe Attempt...
