    Answer:

    9.82 rads/sec

    Explanation:

    We are given;

    Time taken; t = 1.6 secs

    Number of somersaults = 2

    Now, we know that,

    1 revolution = 2π radians

    And number of somersaults is the same thing as number of revolutions

    So,

    Total radians = 2π × 2 = 5π

    Angular velocity = total number of revolutions/time period = 5π/1.6 = 9.82 rads/sec
