VECTOR TEST REVIEW

Today in class Mr. Max gave us our vector test review, which is for our test that is on MONDAY MARCH 23!!



We are allowed to bring in a piece of looseleaf with whatever we want on it to the test.



Mr. Max directed our attention to the government website where there are old ProvincialExams.

The first problem we used as a review was June 2008 written exam, question 13.



The question is Danielle and David are pulling a wagon. Danielle pulls in a direction of N 75 E and David pulls in a direction E 30 S. The resultant force is 80 Newtons due east.



A) Sketch a vector diagram of the forces acting on the wagon, Include all angles. ( 1 mark) Mr. Max reminded us to look at how much the question is worth and evaluate how much you should do. Seeing as this is only for one mark, a 'messy' diagram will suffice as long as you include what is asked for in the question.



B) Determine the magnitude of the force exerted by Danielle. Show your work. ( 2 marks)

hint: use the parallelogram method, because there are two forces acting on one object in different directions.



June 2006 written exam, question 13 is very similar to the question above.



June 2006 written exam, question 12.



A boat on a lake travels a distance of 3km at a bearing of 250. It then turns to a bearing of 155 and travels a distance of 4.5 km.



A) How far is the boat from its starting point? show your work. (2 marks)

(One mark for appropriate strategy and a mark for the correct answer)



B) In what direction should the boat travel to return directly to its starting point? (1 Mark)



June 2007 written test question 3.


Given the two vectors x and y shown below, which diagram correctly shows vector addition?



January 2005 written test question 13



A group of snowmobilers leaves a lodge and travels across a lake at a speed of 40 km/hr for two hours in a direction of N 50° E. The snowmobilers then change direction and travel at 50 km/hr for ½ hour, due south.



A) Calculate the direct distance of the group of snowmobilers from the lodge.Indicate your strategy. (2 marks)



B) A second group of snowmobilers from the same lodge plans to travel to a landmark located 75 km W 25° S. Because of unsafe ice conditions on that part of the lake, the snowmobilers must take an indirect route. Design a route that is 125 km or more that will get them to the landmark. Describe all directions and distances. (3 Marks)





At 3:15 we switched to doing problems from Exercise 4.



Question 8



An aircraft flying horizontally on a heading of 285 is pushed by a wind with a bearing of 15. Angles are measured clockwise from the north. The indicated airspeed of the plane is 300kph. the wind speed is constant at 90 kph.



A) Draw the velocity vectors.



B) After 1 hour and 15 minutes of flight, what will be the aircraft's change in location (nearest half kilometer)?



Exercise 4 Question 5



A river of .62 miles wide is flowing at 6mph. Marie's boat travels at 20mph in still water.



A) in what direction should she point her boat if she wanted to end up going straight across the river (to the nearest tenth of a degree)?



B) To the nearest tenth, what is the actual velocity of Marie's boat relative to the shore?



C) How many minutes will it take her to get across by travelling in this direction?





TEST: MONDAY MARCH 23rd!!!



Have a great weekend, and don't forget to study!
