On Friday, students wrote the vectors test. Absent students will write this test on Monday. They then copied a note about acceleration. We will do a few acceleration problems on Monday. This topic will appear on Thursday's final exam. We will be reviewing Monday-Wednesday. An extensive review is available here on the blog. Please print it this weekend and bring it to class on Monday. Students unprepared for these review classes will not benefit fully from this review opportunity, and final exam marks may be affected as a result. Be smart!

Some velocity problems to get you ready for Friday's quiz....
1) A single-engine plane leaves an airport and flies to another airport 850 km north. It takes 4.0 h to complete the flight. What is the average velocity of the airplane?
2) A truck travels from Toronto due west to London, a distance of 210 km. The total time for the trip is two hours and fifteen minutes. What is the average velocity of the truck?
3) A car travels from Winnipeg east toward Thunder Bay. If the car travels at an average velocity of 90 km/h[E], what will be the displacement of the car 4.5 h later?
4) How many seconds will it take a speedboat travelling at 70.0 km/h[S] to cover a distance of 5.0 km.

Today students were quized by trying an adding vectors question. It's clear that some still need to practice this type of question (practice drawing vector diagrams and using the math method to find resultant deplacement). We then finished the velocity note and did two practice problems. These velocity questions will be continued tomorrow.
