I'm having trouble working this equation. Constants: Mass: 0.138kg Calibration Mass: .050kg Dependent: radius We ran trials on a centripetal apparatus with varying radii and timed the rotation period, then plotted T^2 and radius, found best fit line, and then slope. Slope = 16 Measured centripetal force= .050*9.8 = .490 N What I am having trouble is applying the Cent Force formula F=4(pi^2)rM/T^2 to solve for T^2.
