A force of 2-Newtons will stretch a rubber band 2/100 meters. Assuming that Hooke’s Law applies, how far with a force of 4-Newtons stretch the rubber band? How much work does it take to stretch the rubber band this far?

1 answer

K = 2N./(2/100)m = 100 N/m.

d = 4N. * 1m/100N = 0.04 m.

Work = 2 * 0.04 = 0.08 J.
