You have the following equipment: mass 1: 3.9kg, mass 2: 1.7 kg, spring 1: 5.3 N/m. Rod 1: 0.57m, negligible mass. Give the period of each setup below, rank the lengths of these periods, and explain based on the physical characteristics of each setup why the periods rank as they do. Then draw a position vs time graph that includes two trials of both mass 1 and mass 2 on the spring (i.e. conditions a and c), all on the same graph. In other words, you will have four plots on the same position vs. time axes. In the first trial, the masses are released from rest 10cm vertically above the equilibrium position. In the second trial, the masses are released from rest 7.5cm vertically below the equilibrium position. a. mass 1 on given spring (acting as mass-spring) b. mass 1 on given rod (acting as a pendulum) c. mass 2 on given spring (acting as a mass-spring) d. mass 2 on given rod (acting as a pendulum)
