Let u and v be vectors in R
3
such that ∥u∥ = 30 and ∥v∥ = 5. What can
we best say about |u · v|?
(a) |u · v| > 2.
(b) |u · v| < 30.
(c) 2 < |u · v| < 30.
(d) |u · v| < 150.
(e) |u · v| < 32
Quantities that have magnitude and direction but not position. Some examples of vectors are velocity, displacement, acceleration, and force. They are sometimes called Euclidean or spatial vectors.
