A70 kg person walks at a steady pace of 5.0 km/h on a treadmill at a 5.0% grade. (that is, the vertical distance covered is 5.0% of the horizontal distance covered.) if we assume the metabolic power required is equal to that required for walking on a flat surface plus the rate of doing work for the vertical climb, how much power is required? 370 w 350 w 315 w 300 w
