Final Exam Practice Review You may use a ruler and a calculator for this test. Please show your work for all questions with calculations. Do not forget to include units. 1. What is the difference between scalar and vector quantities? 2. What is the difference between distance and displacement? 3. What is the difference between speed and velocity? 4. Draw a scaled vector diagram, if 30m = 1cm. a. A quantity with a magnitude of 147m, going northwest. 5. 6. b. A quantity with a magnitude of 34m, going east. c. A quantity with a magnitude of 68m, going southwest. d. A quantity with a magnitude of 87m, going south. e. A quantity with a magnitude of 44m, going northeast. Use Figure 1 to answer the questions. a. What is the total distance travelled from point A to point B? b. What is the displacement from point A to point B? c. Draw a scaled vector diagram, if 300m = 1cm. Teacher Gene road her bicycle from school and went north for 700m. She turned west for 300m and then southwest for 400m and reached her destination. The whole trip took about 30 minutes and 11 seconds. Teacher Tanya found a shortcut from where Teacher Gene started to where she ended and travelled 650m in 12 minutes and 2 seconds. (100m = 1cm) Don’t forget to point your arrows and tell me how long each arrow. a. Draw a map of the path each teacher took. b. Find the average speed (m/s) of: i. Teacher Gene ii. Teacher Tanya c. Find the average velocity (m/s) of: i. Teacher Gene ii. Teacher Tanya 7. If I was 45.2m from a wall and the sound of my voice travels at 335 m/s, how long would it take to hear my echo when I shout? Calculate answer in minutes. 8. Clark ran 3200m in 20 minutes and 12 seconds. What is his average speed? Calculate answer in m/s. 9. Susan flew an airplane at 40 m/s. How far did he travel if he flew for 10 minutes and 24 seconds? 10. Find the average velocity if a car started 225m south of town and then ended its journey 2000m south of town in 23.5 minutes. 11. A football player was practicing sprints of 400m. His time was 40 seconds. What is his speed? 12. The same football player came again and ran the same distance, but this time, he ran it in 34 seconds. What is his average speed now? 13. Jenny doesn’t like running. She walked her 2 mile run for PE class in 30 minutes and 33 seconds. Calculate her average speed in mi/hr. 14. Sera likes to play with her echo. She likes to stand in tunnels and shout through it to hear her voice come back to her. If the sound of her voice travels at 335m/s and it takes 30 seconds for her to hear her echo, how far is she from the end of tunnel? 15. Vincent hates taking his time during PE. He likes to run fast. If he runs at a speed of 20 m/s for his 1600m run, how long would it take him to finish?
