2009M2. You are given a long, thin, rectangular bar of known ma ss M and length l with a pivot attached to one
end. The bar has a nonuniform mass density, and the center of mas is located a known distance x from the end
with the pivot. You are to d
In attempt to make a hula-hoop come back to you when thrown you give the hoop some extra spin. You throw the
hoop with an initial velocity vo to the right. You also give the hoop an initial angular velocity o. The hoop
