ahh, of course that mass makes no sense. The equation should be more like
##\frac{1}{0.2555555555}=\frac{1.962}{4\pi^2 m}##
I forgot that the slope is really ##\frac{0.2555555555s^2}{1m}##
Now I can manipulate the equations:
##m=\frac{(1.962)(0.2555555555)}{4\pi^2}##
so the mass of the...
So, in your equations, W is the force of gravity on the hanging weight, which is also the centripetal force on the stopper?
I was, in fact, given the mass of the hanging weight, 200g
In that case, 0.200kg x 9.81m/s2 = 1.962N
Now 1.962N is my Fg and also Fc, I can put it in this as W in...

The purpose of this lab is to determine the mass of a rubber stopper being swung in a horizontal circle.
I made an apparatus that resembles the picture attached, with a string (with a rubber stopper on one end, and a weight on the other end) put...
