    Answer:

    Angular displacement=2π/3.9 rad

    Explanation:

    Given data

    Time t=3.9s

    Required

    The angular displacement during a 1.0 s time interval

    Solution

    In 3.9 second the child covers a full circle=2π rad

    Angular displacement after 1.0 second is given as:

    =\frac{2\pi }{3.9} rad

    Angular displacement=2π/3.9 rad
