Here are two vectors:

a: = (4.0 m)iˆ - (3.0 m)jˆ and b = (6.0 m)iˆ +(8.0 m)jˆ.

 What are (a) the magnitude and (b) the angle (relative to ) of a:  ?

What are (c) the magnitude and (d) the angle of b? What are (e) the

magnitude and (f) the angle of a + b?

(g) the magnitude and (h) the angle of b - d

; and (i) the magnitude and (j)

the angle of ? (k) What is the angle

between the directions of b - a

and a-b ?
