Unformatted text preview: – Displacement vs. distance travelled – Velocity vs. speed • Average vs. Instantaneous Average quantities - Vector Example 4 Answer to Example 4 Practice Set 3 a. An arctic scientist hops on his snowmobile, which is 10m due north of a weather station he was checking. 5 minutes later, he is 350 m due east of the weather station doing 3.5 m/s in a direction 35 degrees south of east. Another 10 minutes later he is 265 m from the weather station in the direction 25 degrees west of south. His velocity at this time is 4.6 m/s going due east. What is his net displacement in unit Answers to Practice Set 3...
