Calculation

1. You have 4 sets of data for t. Calculate the mean of each t. Then you calculate period as
       T = t/50. s_T = s_t
2. From the graphical presentation (see below), you get k. Use equation T = 2pÖM/k to calculate the theoritical value of the period, where M = m +1/3m_s. You should include the mass of the hanger.

Error analysis

Use the data that you get from part 5 to plot the points of the graph.
