I love Google Voice. I have four lines attached to one number. They are still working on transcribing but I have been able to read my messages and if I can't I can still listen.

A small sphere of m = 0.17 kg is suspended by a light string from a vertical post mounted at the edge of a merry-go-round of radius R = 0.35 m. The equilibrium position of the sphere is shown in the figure, with `a' = 0.41 m and `b' = 0.88 m. The axis of rotation is indicated by the dashed line....

OK this one has me totally stumped. My teacher attempted to explain it in class and it made me even more confused. Given:A child of mass m stands at rest near the rim of a stationary merry-go-round of radius R and moment of inertia I. The child now begins to walk around the circumference of the...

A teenager pushes tangentially on a small hand-driven merry-go-round and is able to accelerate it from rest to a frequency of 15 rpm in 9.6 s. Assume the merry-go-round is a uniform disk of radius 2.3 m and has a mass of 730 kg, and two children (each with a mass of 27 kg) sit opposite each other...
