Consider a cyclist coasting down a hill where the road grade is 7%. The total weight of rider and bike is 140 lbf. The rolling resistance coefficient is 0.009 (see H6.4). Using data in text Figure 9.32, determine: a. terminal speed [ft/s, mph] with rider in upright position b. terminal speed [ft/s, mph] with rider in racing position
