This web page is designed to provide some additional practice with the use of scaled vector diagrams for the addition of two or more vectors. Your time will be best spent if you read each practice problem carefully, attempt to solve the problem with a scaled vector diagram, and then check your answer. You are cautioned to avoid making a quick reference to the solution prior to making your own attempt at the solution. Such a habit is likely to fail at nurturing the ability to draw a scaled vector addition diagram. If the solution to these practice problems are still not meaningful, you are encouraged to obtain some on-line help in The Physics Classroom. Visit the page on vector addition.

NOTE: Since your answers were determined using a scaled vector diagram, small errors in the measurement of the direction and magnitude of any one of the vectors may lead to small differences between your answers and the correct ones which are shown here. Do not* have a cow.*

**1. **Add the following vectors and determine the resultant.

3.0 m/s, 45 deg and 5.0 m/s, 135 deg

5.0 m/s, 45 deg and 2.0 m/s, 180 deg

6.0 m/s, 225 deg and 2.0 m/s, 90 deg

4.0 m/s, 135 deg and 4.0 m/s, 315 deg

5.0 m/s, 45 deg and 2.5 m/s, 135 deg

7.0 m/s, 0 deg and 2.0 m/s, 90 deg

8.0 m/s, 330 deg and 4.0 m/s, 45 deg

2.0 m/s, 150 deg and 4.0 m/s, 225 deg

3.0 m/s, 45 deg and 5.0 m/s, 135 deg and 2.0 m/s, 60 deg

2.0 m/s, 315 deg+ 5.0 m/s, 180 deg+ 2.0 m/s, 60 deg= 2.61m/s, 173 deg

4.0 m/s, 90 deg and 2.0 m/s, 0 deg and 2.0 m/s, 210 deg

2.5 m/s, 45 deg and 5.0 m/s, 270 deg and 5.0 m/s, 330 deg
