    A diver can change her rate of rotation in the air by "tucking" her head in and bending her knees. Lets assume that when she is stretched out straight she is rotating at 1 revolution per second. Now she goes into the "bend and tuck", effectively shortening the length of her body in half. What will her roation be now?

    a. 5Hz
    b. 4Hz

    where I = ...

    Solution Summary

    The solution offers a quick, clear answer as to how many rotations a diver will go through in the 'bend and tuck' position using the law of the conservation of angular momentum and the associated formula as well as some written explanation.
