Step 1

From part 1, we know that A is a vector with magnitude 2 cm and direction 30°, and B is a vector with magnitude 3 cm and direction 150°. To write A in unit vector notation, we need to find the components of A in the x and y directions. The x-component of A can be Show more…

Texts: I'm confused with direction for 3 and 5 because I got 2.6 cm for magnitude for 3 and 4.3 for 5. Part 1 is just drawing the vector on the graph, it plays no effect. The measurements were stated the first time on part 1. Styles Voice Sensitivity Editor Add-ins Recall the following vectors from part 1: 2 cm at 30° and 3 cm at 150°. Write A and B in unit vector notation. 2. Find C = A + B and express it in unit vector notation. 3. Find the magnitude and direction of C. Do these results match what you got from part 1? 4. Find D = A - B and express it in unit vector notation. Find the magnitude and direction. Do these results match what you got from part 1?
