9.100 (Introduction to Fluid Mechanics, 7th Ed.; Fox, Pritchard, McDonald)

A cyclist is able to attain a maximum speed of 30 km/hr on a calm day. The total mass of rider and bike is 65 kg. The rolling resistance of the tires is F_R = 7.5 N, and the drag coefficient and frontal area are C_D = 1.2 and A = 0.25 m^2. The cyclist bets that today, even though there is a headwind of 10 km/hr, she can maintain a speed of 24 km/hr. She also bets that, cycling with wind support, she can attain a top speed of 40 km/hr. Which, if any, bets does she win?
