Use the following example to describe distance and displacement.  A person walks east for 3 miles then turns around and walks west for 2 miles. 5.  Why has a person that has run 1 mile race on an oval track not been displaced? 6.  Give an example where vectors would be added. Where they would be subtracted and also where they would be multiplied. 7.  Give the standard unit for each of the following measurements. a.  distance b.  time c.  force or weight d.  mass e.  speed f.  velocity g.  acceleration Solve the following questions. 8.  A high speed train travels at 300 km/h.  How long would it take the train to travel 1650 km? 9.  You are traveling on an interstate at 65 m/h.  You notice that a semitruck is traveling slower that you and you decide, that when it is safe, to switch lanes to pass the truck.  You notice that your speed when passing the truck is 70 m/h.  If it took you 2.5 s to pass safely what was your acceleration?
