In SI units, speeds are measured in meters per second (m/s). But, depending on where you live, you’re probably mole comfortable of thinking of speeds in terms of either kilometers per hour (km/h) or miles per hour (mi/h). In this problem, you will see that 1 m/s is roughly 4 km/h or 2 mi/h, which is handy to use when developing your physical Intuition. More precisely, show that (a) 1.0m/s=3.6km/h and 1.0m/s=2.2mi/h .

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.)
