    You have 1000 * 2π radians in 49.7 ms, so the angular velocity is

    ω = 1000*2π / 0.0497s = 1.26E5 rad/s

    also called the angular velocity

    1000/.0497=20,120 RPM

    1000 revs in 0.0497 seconds

    so, (1000/0.0497) revs/second

    i.e. 20121 revs/second...linear velocity

    And 20121 x 2π rads/sec

    i.e. 40242π rads/sec...angular velocity

    f = (1000 rev)(1 / 0.0497 s) = 2.01 x 10^4 rev/s
