Sammie’s Spectral Vector
Sammie says she wants more practice with vector addition. OK, she didn’t exactly ask for it, but a little practice
won’t hurt her, or you! Here it is. If you print this off in black and white, trace over the vectors with the
appropriate color.
1-4: Add the vectors using color-coding, with the resultant in black. Ruler and protractor are not required; just
eyeball the vectors.

Yeah, this one is a bit different, but see if you can do it…

5. A ghost plane flies 50.0 miles with a heading of 20.0o N of W, at a speed of 100.0 mph. The plane makes an
abrupt turn, and then accelerates uniformly from 100.0 mph to 160.0 mph in 0.500 hours, heading of due
east.
A) What is the plane’s displacement in the second leg?
B) Use a scale diagram to find the plane’s total displacement (magnitude and direction) for the entire trip.
Color-code your diagram, with the resultant in black.
Answers: 5. A) Δx2 = 65.0 mi. due east.
B) Δxtot = 24.8 mi, 43.5o N of E
