Before answering the questions below, please read the lab handout “Physics 161 Lab 6” and “Statistics Handout”. These documents can be found by clicking on the “Files” link on the Canvas front page for PHYS 161. There is no preliminary survey for Lab 6.

1) What are the units for the spring constant, k, in Hook’s Law?

2) List values of masses used and the corresponding displacements from the equilibrium length from Task A.

3) Show the 10 calculated values for the spring constant from the measurements taken in Task A. Calculate the average and standard deviation of these 10 values for ‘k’.

4) List values of masses used and the corresponding displacements from the equilibrium length from Task B.

5) Show the 10 calculated values for the spring constant from the measurements taken in Task B. Calculate the average and standard deviation of these 10 values for ‘k’.

6) Calculate the DS value to compare the results from Task A and Task B. For the denominator use standard deviation rather than standard error of the mean, so it should be equal to [( stdevTask A)^2 + ( stdevTask B)^2]^0.5
