A laboratory measurement of the coordinates of the ends of a moving meterstick, taken at the same time in the laboratory, gives the result that one end of the stick is 0.9918 m due north of the other end. If the stick is moving due north, what is its speed with respect to the lab?

A 280-kg flatcar 22 m long is moving with a speed of 6.0 m/s along horizontal frictionless rails. A 95-kg worker starts walking from one end of the car to the other in the direction of motion, with speed 2.5 m/s with respect to the car. In the time it takes for him to reach the other end, how far has the flatcar moved?

LAB 1 PROBLEM 1: INTRODUCTION TO MEASUREMENT AND UNCERTAINTY Welcome to 1101 Physics Laboratory! This lab exercise is meant to introduce you to measurement procedures, uncertainties in measurement, and the computer software that you will be using throughout the course. It will be worth your time to read through this entire lab and the next one as there are many helpful tips and references that you may want to use in later labs.

Apgar scores are a measurement of an infant’s overall health taken a few minutes after birth. The score ranges from 0 (death) to 10 (perfect health) and is based on tests of the baby’s heart rate, breathing rate, muscle tone, color of skin, etc. A critic gives three reasons why the Apgar score isn’t a perfect measurement: REASON 1 – There are many other important facets of health that aren’t measured by the score. REASON 2 – A doctor’s rating...
