    Answer:

    a) 3.7 x 10^-3 s

    b) 230.41 rad/s

    Explanation:

    The angular speed N = 2200 rpm (revolution per minute)

    ==> 2200/60 revolutions per sec = 36.67 rps

    The total angle turned in one second = 36.67 x 360° = 13201.2°

    if it takes 1 sec to revolve 13201.2°

    then it will take t sec to rotate 49.0°

    time t = 49/13201.2 = 3.7 x 10^-3 s

    conversion to rad/s = 2πN/60 = (2 x 3.142 x 2200)/60 = 230.41 rad/s
