1. For a springmass system displaced from equilibrium, where k is the spring constant. A. Substituting y(t) = A cos(a)t + 9b) and setting yo = 0, solve for angular frequency, (0. Consider this equation for the angular frequency of the springmass system. How would you expect a) to change if you vary the amplitude, the mass, or the spring constant parameters (changing only one parameter at a time). Explain your predictions. B. If you measure the frequency of oscillation, f, for different masses suspended on the same spring what values would you use to plot a graph in order to determine spring constant, k? Hint: Ideally, you want to analyze a linear graph. What do you need to do with your data to be able to do so? Prepare a table for taking measurements
