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.)
A fast train bump into a slow train going the same direction, and they get coupled together. The fast train was initially going 6.93 meters per second and the slow train 3.1 meters per second. What is the final speed (in meters per second) once the two are coupled?
