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.)
