Work is being done to stretch the packing tape. The force of the rubber band is modeled with an expression
F (x) = - Fo [(L + x)/L − L2 /(L + x)2],
where Fo = 9.2 N, the elastic length of the elastic band L = 0.95 m and the x is the change in the length of the elastic band.
Determine how much work is done on the elastic band when stretching the distance d = 0.55 m

A bungee cord is essentially a very long rubber band that can stretch up to four times its unstretched length. However, its spring constant varies over its stretch [see Menz, P.G. “The Physics of Bungee Jumping.” The Physics Teacher (November 1993) 31: 483-487]. Suppose an unstretched bungee cord has a length l0 = 23.3 m and during a bungee jump it stretches so that its maximum total length is l = 53.7 m. Suppose that bungee cord behaves like an...

(1 point) Finding the work done in stretching or compressing a spring. Hooke's Law for Springs. According to Hooke's law, the force required to compress or stretch a spring from an equilibrium position is given by F(x) = kx, for some constant k. The value of k (measured in force units per unit length) depends on the physical characteristics of the spring. The constant k is called the spring constant and is always positive. Part 1. Suppose that it takes...

Example 13.4.2 Sample Problem Work done by a gravitational force Two stationary particles with mass m = 3.00 x 10-13 kg and m2 = 5.00 x 10-13 kg are initially separated by distance r = 2.60 x 10-3 m. We double their separation and then they are stationary again. We want to calculate how much work we do in increasing the separation and how much is done by the gravitational force between the particles. We...
