Final answer:
To calculate Janelle's calorie burn during the 100-meter sprint, we need specific information about the energy consumption rate for this activity. However, based on data from Table 7.5, a well-conditioned athlete can burn approximately 35 kcal per minute while sprinting.
Step-by-step explanation:
To calculate the number of calories burned by Janelle while running the 100-meter sprint, we need to know the energy consumption rate for this activity. Unfortunately, the information provided does not include specific data for the 100-meter sprint. Therefore, we cannot determine the exact number of calories burned by Janelle during the sprint. However, it is worth noting that a well-conditioned athlete can burn approximately 35 kcal per minute (2415 watts) while sprinting, according to Table 7.5. Therefore, option (b) 2000 calories would be a reasonable estimate for Janelle's calorie burn during the 100-meter sprint.
