Power is defined as energy per time, so it is the number of joules, or calories, a system produces or uses in a given time span. The SI unit for power is the watt (W) and 1 W of power is equal to 1 joule per second. A reasonably fit human can generate approximately 200 W of output muscle power on a continuous basis (assuming they have adequate hydration, access to food, and are allowed to sleep for 4-6 hrs every 24 hrs). A Carl's Jr. 1/2-lb Guacamole Bacon Thickburger, large fries, and large Oreo Cookie Malt contain approximately 2460 CaloriesLinks to an external site.. How long would it take someone who was generating 2.0 x 102 W of power on a stationary bicycle to expend 2460 Cal? (Express your answer with the correct number of significant digits.) Hint: remember a food Calorie is a kilocalorie and that there are 4.184 kJ/kcal (or 4.184 J/cal) Group of answer choices 14 hrs 56 s 5.146 x 104 s 51 s 16 hrs
