Q. Bicyclists in the Tour de France do enormous amounts of work during a race. For example, the average power per kilogram generated by Lance Armstrong (m = 75.0 kg) is 6.50 W per kilogram of his body mass. i. How much work does he do during a 110-km race in which his average speed is 12.5 m/s? ii. Frequently, the work done is expressed in nutritional Calories rather than in joules. State the work done in part (a) in terms of nutritional Calories, noting that 1 joule = 2.389 10-4 nutritional Calories.
