Today we started off by correcting the lilac coloured sheet "Grade 11 Physics: Dynamics-Vectors". Remember that you have to include the direction or unit in the answer or you'll lose marks. Then we went over the backside of the page, and the practice questions are for homework and we'll go over them tomorrow.
1. A boat aims itself due east at 15km/h across a northern current of 5.0km/h. What is the boat's resulting velocity?
2. What is a ball's actual velocity if after 2 seconds in the air, it has a Vy = 20m/s up and Vx = 10m/s?
3. What is a kite surfer's velocity if the waves are moving him East at 1.5m/s and the wind is blowing him North at 4m/s?
After we corrected questions 1-5 on Newton's Second Law (page 43) of the Dynamics booklet, and if you haven't finished questions 6-9 have them done for tomorrow. Then Ms K assigned pages 12 (Net Force) and 33 (Transparency 4-4 Weight and Normal Force) in the Dynamics booklet to be done for tomorrow as well.
If you need a protractor you can buy one from Ms K for $1. And don't forget the test on Friday!
