a bicyclist rides off a flat roof at 13.4m/s, the roof is 3.6m above the ground, how far from the edge of the building does the bicyclist land? round the answer to the nearest meter.

  • college physics - ,

    h = Vo*t + 0.5g*t^2. = 3.6
    0 * 4.9t^2 = 3.6
    t^2 = 0.735 .
    Tf = 0.857 s. = Fall time.

    d = Xo * Tf = 13.4m/s * 0.857s. = 11 m.
