A68 kg hiker walks at 5.0 km/h up a 3% slope. the indicated incline is the ratio of the vertical distance and the horizontal distance expressed as percentage.

what is the necessary metabolic power?

Explanation:

As we know that the slope of the inclination is 3%

so we can say that

since it is very small so here we can take approximation as

so we need to find the metabolic power which is given as

so here we have

now we have

5 w for 1hr = 5x60x60 joules=300x60=3000x6=18,000j as total energy conversion. efficiency of bulb needed for radiant to thermal within 18000

it breaks and dirupture other materials and other sencews from the bottom
