Calculate the value of the slope from your graph (Graph-1) 22. Now calculate k the spring constant from k = g/slope 23. Make a plot of the period squared 72 (column 8) versus static displacement (column 4) 24. Calculate the value of the slope from your graph and compute the percent error 4JC 2 between it and the theoretical value of k= PART II: 1. Set the mass you are going to use for this as 150 g and all you have to do for this part is to pull the spring along with the mass down and record how long would it take for 10 cycles. 2. Second trial do the same as above step but pull the spring a little more down. 3. Take 3 readings by pulling the spring a little longer every time and leaving it to bounce.
