Description
Basic properties of vectors.
Reading: Chapter 1, Section 1.5
Instructions
On Question 1, look carefully at each vector when deciding whether its magnitude is the same
as another; round to the nearest unit.
On Question 6, remember that a unit vector is a vector whose magnitude is 1. The numbers
have been rounded to 3 significant figures, so the magnitude of a true unit vector might not be
exactly equal to 1.000.
Answer all questions carefully before submitting the assignment, then correct any errors that are
reported. You can make 5 submissions.
