73 x (m) -2 3 Section 6.7 Elastic Potential Energy 74 69. The tension in a ligament in the human knee is approximately proportional to the extension of the liga- ment, if the extension is not too large. If a particular ligament has an effective spring constant of 150 N/mm as it is stretched, (a) what is the tension in this ligament 75 when it is stretched by 0.75 cm? (b) What is the elas- tic energy stored in the ligament when stretched by this amount? lnoun as an atomic force microscope 2.
