Was there any evidence in the collected data that hinted a sinusoidal function is not a good model for this motion?
A) Performing a Fourier analysis to identify dominant frequencies in the data.
B) Conducting regression analysis to fit a sinusoidal function and assess the goodness of fit.
C) Comparing the residuals from the sinusoidal model to check for systematic patterns.
D) Utilizing statistical tests like the Chi-square test to assess the deviation of observed data from a sinusoidal pattern.
