Do your results for Part I represent equilibrium in each case, within a reasonable degree? If any cases do not, explain what may have caused these trials to deviate from equilibrium, and how to improve the results. Also try to take note of any patterns in the net force columns, and attempt to explain why these patterns might exist. For Part II, do the velocities that you found using the hang time and the force data agree? Does this suggest that Newton's Second Law does indeed hold during the act of jumping? Attempt to explain any discrepancies, in detail
