## Homework Statement

The lab: Centripetal Force Lab

a Rubber stopper is moving in a horizontal circle at a constant radius and it is attached to a string where at the bottom, there is a mass where the mass is 100g, 150g, 200g, 250, and 300g (can see image attached)

from the lab, I collected data for each mass and now we have to plot Fc vs v^2 and draw a line of best fit and find the slope of the line. In relation to the line, try to find the mass of the rubber stopper.

(i attached another image that has my data points)

## Homework Equations

I'm not too sure but

Fc= mv^2/r

## The Attempt at a Solution

I keep on finding that the equation is 0.156 on excel but Idk where to go from here. [/B]
