    motion of ball

    If a ball were thrown horizontally with a velocity of 101.0 mi/h, how far would it fall vertically by the time it reached the ground, 60.5 ft away?

    t = \frac{\Delta x}{v_x}
    calculate t ... recommend you change mph to ft/sec

    \Delta y = v_{y0}t - \frac{1}{2}gt^2

    since v_{y0}=0 ...

    \Delta y = -\frac{1}{2}gt^2

    using t calculated above, calculate \Delta y

    note that g = 32 \frac{ft}{s^2}
