Problem 67PE

Your Own a person climbing and descending stairs. Construct a problem in which you calculate the long-term rate at which stairs can be climbed considering the mass of the person, his ability to generate power with his legs, and the height of a single stair step. Also consider why the same person can descend stairs at a faster rate for a nearly unlimited time in spite of the fact that very similar forces are exerted going down as going up. (This points to a fundamentally different process for descending versus climbing stairs.)

Step-by-Step Solution:

Step-by-step solution Step 1 of 4 Consider a man climbing up a continuous flight of stairs. If he weighs 76 kg and each stair is 47 cm high, then find out the long term rate at which he can climb the stairs. Assume that the man under consideration can generate a maximum power of 400 W with his legs.
