    Answer:

    Explanation:

    height of the building h = 15 m

    initial vertical velocity u = 0

    v² = u² + 2 g h

    u = 0 , final velocity after falling height h

    h = 15

    v² = 2 x 9.8 x 15

    v = 17.14 m /s

    . Time of fall be t

    h = 1/2 g t²

    15 = 1/2 x 9.8 x t²

    t = 1.749 s

    This time will be required for truck to come under the building .

    speed = distance / time

    distance = speed x time

    = 22 x 1.749

    38.5 m

    Truck should be at a distance of 38.5 m . when the stuntman starts falling .
