In class, I stood on a turn table with 10 lb weights (that's 4.54 kg) in my outstretched arms. Suppose my moment of inertia was 6.57 kg m². A student volunteer spun me so that I had an angular speed of 2.92 rad/s, and then I brought my arms into my body. Doing so caused my moment of inertia to change to 2.74 kgm². What was my angular speed after I brought my arms in?

1.22 rad/s 6.17 rad/s 8.00 rad/s 7.00 rad/s
