Question

The graph shows thetension in a rubber band as it is first stretched and then allowedto contract. As you stretch a rubber band, the tension force at aparticular length (on the way to maximum stretch) is larger thanthe force at that same length as you let the rubber band contract.That is why the graph shows two separate lines, one for stretchingand one for contracting; the lines are not superimposed as youmight have thought they would be.

a) Make a rough estimateof the total work done by the external force applied to the rubberband for the entire process.
b) If the rubber band obeyed Hooke's law, what would the answer toa) have to be?
c) While the rubber band is stretched, is all of the work done onit accounted for by the increase in elastic potential energy? Ifnot, what happens to the rest of it? [Hint: Take a rubber band andstretch it rapidly several times. Then hold it against your wristor your lip.]
