An elite Tour de France cyclist can maintain an output power of 470 W during a sustained climb. At this output power, how long would it take an 84 kg cyclist (including the mass of his bike) to climb the famed 1100-m-high Alpe d'Huez mountain stage? Neglect any friction.
Question: Ted is a cyclist on the Tour de France. One year ago, his hematocrit was 45%. Now, his hematocrit is 50%. Which of the following statement is TRUE? Question options: Ted probably has anemia. Ted may have taken erythropoietin (EPO) in the past year. The resistance of Ted's blood flow is decreased compared to a year ago. Ted's red blood cells concentration is reduced compared to a year ago. The viscosity of Ted's blood is reduced compared to a...
Question 2 (15 marks total) It is a rainy day at the Tour de France (a famous bicycle race). In this stage of the race, there is a sprint finish. With about 100 m to go, the cyclists increases their speed from about 60 km/hr to 70 km/hr in a manner of seconds. The resulting acceleration is 0.6 m/s for the cyclist shown. Given the cyclist weighs 63 kg, the bike weighs 7 kg, us = 0.6, U = 0.5...
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 178-km race in which his average speed is 11.5 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...
Jason, a 60 kg cyclist, is pedaling his bike at a good clip, using a total energy of 400 W. As he exercises, his body will start to warm up, and he will perspire to keep himself cool. 1) Assuming Jason’s pedaling has a typical 25% efficiency, by how much would his body temperature rise during 1.0 h of cycling if he had no means of exhausting excess thermal energy? 2) Assume that the only means by which his body...
JUST CHECKING In the 2004 Tour de France, Lance Armstrong made history by winning the race for an unprec- edented sixth time. In 2005, he became the only 7-time winner and set a new record for the fast- est average speed-41.65 kilometers per hour-that stands to this day. In 2012, he was banned for life for doping offenses, stripped of all of his titles and his records expunged. You can find data on all the Tour de France races in...
