5.22 Cylindrical coordinates and vector differentiation via angular velocity. (Section 6.1). Referring to Hw 5.21, use the golden rule for vector differentiation (given below) and A's an- gular velocity in N (which is NA= 0) to calculate the time-derivative in N of p. Result: Just calculate! {=1st Ndp Adp N-A + x p ax + a + az ay Wow, the golden rule for vector differentiation is easier and more efficient than Hw 5.21!

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.
