1. Kenny is climbing the stairs of his apartment building for exercise. Kenny weighs 83 kg. There are 8 steps in each flight and the height of a single step on the staircase is 11 inches. He climbs the flight of stairs in 3.4 seconds. a.) calculate the long-term rate at which stairs can be climbed considering the given information.(how long can be sustained in stair per second) b.) Why does Kenny descend stairs at a faster rate for a nearly unlimited time although very similar forces are exerted descending as they are ascending?(This points to a fundamentally different process for descending versus climbing stairs.)

Given data:
The height of each step is 11 inches and there are 8 steps in each staircase.
Total height is .
He climbs this height in 3.4 seconds.
Therefore his velocity is
Each step is 11 inches, 0.2794 m. Time to sustain in the stair per second is
Step by step
Solved in 2 steps
