12.18

Thursday December 18, 2008 The class started off with a graded daily question: A catapult fires a pumpkin at 30 miles per hour in the 130 degree direction. Using trig, calculate how fast the pumpkin was traveling when fired horizontally and vertically. Show all work. After doing the daily question we reviewed and the correct answers for the adjacent side is 19.3 miles/hour and the opposite side was 23.0 miles/hour. After the daily question we were reminded of the unit 5B test tomorrow, don’t forget your protractor! The test will be approximately 30 points and will consist of multiple choice, fill in the blank, trig problems, and vector problems. It will focus on the new trig way of solving problems and overall concepts. We reviewed our work from yesterday (pg. 25) and received new practice problems on page 26. If you are struggling with the concepts of vectors page 27 and 28 will be helpful.
