Unformatted text preview: horizontal at an angle α as shown. ±ind an expression for the maximum coasting speed (no pedaling, no braking, assume no friction). The total mass (of the cyclist and the bike) is m , the drag coe²cient is c D and the e³ective frontal area is A . Assume sea-level air. α (b) ±or an upright bike, White (Table 7.3) gives c D A = 0.51. ±or m = 80 kg and α = 5 degrees, Fnd the maximum coasting speed in m/sec and also in mi/hr. (c) For a racer on a road bike, White gives c D A = 0.30. Repeat the calcula-tion of part (b) for the racer. 3. White (7th Ed.) Problem 7.56. 4. White (7th Ed.) Problem 7.80. 5. White (7th Ed.)
