I have a circular motion lab, in which we spin a rubber stopper attached at one end and a mass at the other end of a string. We calculate the period by the recording the time it takes for 20 revolutions. And we figure out the force Fc.(adsbygoogle = window.adsbygoogle || []).push({});

So we do three different graphs:

one for Fc vs Period

2nd for Radius vs Period

3rd for Mass vs Period

And we get the following eqn's of the line once, notice I have subsituted for x and y from the above variables.

Fc = 3.0381/T^2 - 2.6566

R=1.5962T^2 - 0.0778

m= 0.1031T^2 - 0.0024

The problems is that I have to Write each eqn in terms of T (period) and then write One final eqn that relates Fc, m, r and T. How do i do this?
