**Problem Statement:**A 70 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?**Explanation:**This problem involves calculating the power output required for a person to walk on a treadmill with a specific incline. It considers both the energy needed to walk on a flat surface and the additional energy required to overcome the incline.To solve the problem, the following aspects should be evaluated:1. **Power for Flat Surface:** - Determine the power needed for walking at 5.0 km/h on a flat surface.2. **Power for Incline:** - Identify the rate of energy required to climb vertically since the treadmill is at a 5.0% grade. This involves calculating the vertical component of the walking speed and converting that into a power requirement.3. **Total Power:** - Sum the power for the flat surface and the power for the incline to get the total power required.**Note:** The formula for calculating the power due to the incline is generally derived from the relationship: Power = work done/time, where work done is the force exerted (weight of the person) times the vertical distance covered. On flat ground, a 70 kg person requires about 300 W of metabolic power to walk at a steady pace of 5.0 km/h (1.4 m/s). Using the same metabolic power output, that person can bicycle over the same ground at 15 km/h.
