Center mass/angular velocity vector

[iknowu99]

Homework Statement

baton like figure - weight at (0,A) that has a mass M, second weight at origin (0,0) with weight 2M. These are the end points of the baton and that is it for this baton weight/location. The 2M weight has a velocity V towards the positive x axis. The goal is to locate the M mass with respect to time T.

Homework Equations

not sure...

The Attempt at a Solution

not sure...i think it spins in one spot... the top mass might have a velocity twice as fast...but not sure about this either...since no force then the center of mass located at (0,a/3) will stay there..but that's all i have...

Hi iknowu99! Welcome to PF!

Can you give us the full question?

We need to know how this happened … for example, was there a sudden force along the x-axis hitting the 2M?

that's what i thought at first but there is no force applied. the question is: provide the X,Y at time T for the mass M.
