### Applied 40S April 30, 2009

1. 1. Vector Applications Magic orienteering by ﬂickr user AlbeJTD
2. 2. A ball is thrown horizontally against a wall with a velocity of 10 m/s. It rebounds with a velocity that has a magnitude of 75% of the initial velocity. Visualizing the Process ... Sketch two vectors to represent the two velocities. > l ai -t The Triangle Method -to > p ti Resultant of Forces (Addition of Vectors) http://www.walter-fendt.de/ph14e/resultant.htm
3. 3. The Triangle Method ... HOMEWORK We use the triangle method when the vectors are arranged tip-to-tail. 6cm Scale: 1 cm = 2 km 10cm RESULTANT 23.4 km 59° S of E RESULTANT 11.7 cm 59° S of E Remember, we use measurements with a ruler and protractor to ﬁnd the quot;answers.quot;
4. 4. You try ... HOMEWORK Add each pair of vectors using the triangle method. Find Find is 3 meters east is 3 meters southwest is 4 meters north is 4 meters west
5. 5. Use the TRISOLVE program to solve each of the following problems.
6. 6. You try ... HOMEWORK Add each pair of vectors using the triangle method. Find is 3 meters southwest is 4 meters west Finish this problem for HOMEWORK
7. 7. A man walks 350 m north, then 175 m east, and then 150 m south. How far and in what direction is he from his starting point? Round your answers to the nearest whole numbers. HOMEWORK
8. 8. Jack jogs north at 15 km/h for 30 minutes, and then turns east and jogs at 12 km/h for 20 minutes. HOMEWORK (a) How far has he jogged in total? (b) How far is he from his starting point? (c) In what direction does he need to go to return directly to his starting point?
