80. (a) Using Eq. 7-32, the work becomes W = 9 2 x 2 x 3 (SI units understood). The plot is shown below: (b) We see from the graph that its peak value occurs at x = 3.00 m. This can be verified by taking the derivative of W and setting equal to zero, or simply by noting that this is where the force vanishes.
