Question

Please help, thanks.

Chapter 01, Problem 26 GO Vector A has a magnitude of 64 units and points due west, while vector B has the same magnitude and points due south. Find the magnitude and direction of (a) A B and (b) A B. Specify the directions relative to due west. (a) Magnitude and direction of A + B = and (b) Magnitude and direction of A - B- and LINK TO TEXT

Answer 1

Taking unit vector along east as x and unit vector along north as y,

Vector A = - 64 x and

Vector B = - 64 y
