Construct a Table indicating the position x2x vk,gntx91e of the mass in Fig. 11x+ h;qsk)mi- h–2 at times t = 0k) +msxhq;h i-,t = $\frac{1}{4}T$,$\frac{1}{2}T$,$\frac{3}{4}T$,T and $\frac{5}{4}T$,where T is the period of oscillation. On a graph of x vs. t, plot these six points. Now connect these points with a smooth curve. Based on these simple considerations, does your curve resemble that of a cosine or sine wave (Fig. 11–8a or 11–9)?
