if the energy bar was his only fuel, how far could a 68 kg person walk at 5.0 km/hr ? the metabolic power (W) of a 68 kg individual walking at 5 km/hr is 380 W.
Part B How much metabolic energy is required for this person to walk at a speed of 5 km/h for 69 min? Assume that metabolic power of this walking person is 380 W Express your answer using two significant figures. Submit Request Answer
2. Suppose a car travels 108 km at a speed of 20.0 m/s, and uses 2.20 gallons of gasoline. Only 30% of the gasoline goes into useful work by the force that keeps the car moving at constant speed despite friction. (The energy content of gasoline is 1.3 ✕ 108 J per gallon.) (a) What is the force exerted to keep the car moving at constant speed? N (b) If the required force is directly proportional to speed, how many...
