The speed limit on some interstate highways is roughly 100 km/h. (a) What is this in meters per second? (b) How many miles per hour is this?
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 .
An advertisement for the newest model of a Mercedes sports claims the car can go from 0 to 60 miles per hour (mph) in just 3.3 seconds! a) How many meters per second (m/s) is 60 mph? b) In m/s 2 (sometimes written as m/s/s also, just so you know), what is the supposed acceleration of the sports car? c) Impressed by this claim, Sherry buys one. She hops into her new Mercedes sports car and steps on the gas. She’s an engineer and did the math later on; she discovered that her car’s acceleration is 6.7 m/s2 . i) Is her car’s acceleration faster or slower than the advertisement claims it should be? ii) In seconds, how long did it actually take for Sherry’s car to reach 60 mph

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.)
