Physics II Labs: SHO Mass on Spring Position and Velocity vs Time EQN Fit Graph 200 Grams Mass

Because Canvas is so bad at copying images/graphs/etc over, here is another image used in one of my quizzes:

 This is a pair of graphs. The first is position as a function of time, and the second is velocity as a function of time. Both are for the same motion, which involved a 200 gram mass placed at the end of a spring and then displaced from equilibrium (x = 0). A sine function has been fit to each of these graphs.
