In the final section of the lab, the student is asked to investigate the energy distribution of the spring system described previously. The student pulls the mass down an additional 20.6 cm from the equilibrium point of 27.5 cm when the mass is stationary and allows the system to oscillate. Using the equilibrium point of 27.5 cm as the zero point for total potential energy, calculate the velocity and total potential energy for each displacement given and insert the correct answer.
