A 68 kg hiker walks at 5.0 km/h up a 8 % slope. The indicated incline is the ratio of the vertical distance and the horizontal distance expressed as percentage. For the steps and strategies involved in solving a similar problem, you may view a Video Tutor Solution. What is the necessary metabolic power? Hint: You can model her power needs as the sum of the 380 W power to walk on level ground plus the power needed to raise her body by the appropriate amount. Assume that the efficiency of the body in using energy is 25% Express your answer with the appropriate units. P= Value Units ?
