Review Example 13, in which the work done in drawing the bowstring in Figure 6.20 from s = 0 to s = 0.500 m is determined. In part b of the figure, the force component F cos θ reaches a maximum value at s = 0.306 m. Find the percentage of the total work that is done when the bowstring is moved
(a) From s = 0 to 0.306 m
(b) From s = 0.306 to 0.500 m.
