2. ### In an oscillation lab NYC, they ask us to find an expression for the period "T" as a function of the spring constant "k" and the mass "m"?

Well you already have the expression: 2 pi sqrt(m/k). You want a linear plot with the slope being k. A linear plot...^2 = (2*pi)^2 * m/k I could now say y = T^2, x=m, a=(2*pi)^2/k and b=0. So I can make a plot with T^2 on the y-axis, m on...
