Homework Help: Centripetal force

  1. Oct 28, 2011 #1
    1. The problem statement, all variables and given/known data
    How do you calculate the mass from slope of a line T^2 on y axis and 1/f on x axis??



    2. Relevant equations
    4π^2mr/fc


    3. The attempt at a solution
    I don't know how to attempt this. I have a data table and the graph has y=0.7385x-0.0254.
    Obviously 0.7385 is the slope but I do not know what to use to get the mass.

    What is the equation of the graph in terms of physical quantities?

    Nevermind, it is too late now. I will just have to take a lower grade on my report. Thanks anyway.
