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. (a) how much work does he do during a 164-km race in which his average speed is 11.1 m/s? (b) often, the work done is expressed in nutritional calories rather than in joules. express the work done in part (a) in terms of nutritional calories, noting that 1 joule = 2.389 x 10-4 nutritional calories.
