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.

Here is some info on your final exam.
Exam Notes
Here is an exam review.
Today, students examined the sample velocity problems on page 170 and then answered #2-5 on page 171. These are to be completed for homework if not done.

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.

Today we reviewed how to add vectors along a straight line. We then worked through questions #1-5 on page 165. Near the end of the class, students began copying a note on velocity. This note will be continued on Monday. There is no homework this weekend, so be sure to finish up any projects that you have due next week in your other classes!
On Thursday, students wrote the speed lab. Absent students will write this test on their first day back to class.

Today we attempted to take up the speed review, which was to be done as a preparation for Thursday's speed test. Unfortunately, only about 3 students had the problem sheet completed. The remainder of the students will need to prepare tonight for the test.
