I would appreciate some clarification with the conceptual side of the problem. Am I setting up a problem where these two bodies are orbiting about the CM, or am I treating these two bodies as if they ARE the CM and the CM is orbiting about some arbitrary origin?

(a) Using elementary Newtonian mechanics find the period of a mass m1 in a circular orbit of radius r around a fixed mass m2 (solved, but placing for context).
(b) Using the separation into CM and relative motions, find the corresponding period for the case that m2 is not...
Oops. Yes. There is nothing in contact with the ball (other than the fluid, which is air) and so there is no normal force. I meant to say gravitational force, sorry.
The two forces acting upon the ball whilst it rises are the gravitational and the fluid resistance, which are both opposing the...

A baseball of mass m is thrown straight up with an initial velocity v0. Assuming that the air drag on the ball varies quadratically with speed (f = cv^2), show that the speed varies with height according to the equations.
Where x_{0} is the highest point and k = c/m...
