Chapter 4.4, Problem 90E

Physiology. In a study on the speed of muscle contraction in frogs under various loads, researchers found that the speed of contraction decreases with increasing loads. More precisely, they found that the relationship between speed of contraction, S (in centimeters per second), and load w, (in grams), is given approximately by

     $S\left(w\right)=\frac{26+0.06w}{w}w\ge 5$
