Chapter 3, Problem 48P

GO Two vectors $\stackrel{\to }{a}$ and $\stackrel{\to }{b}$ have the components, in meters, a_x = 3.2, a_y = 1.6, b_x = 0.50, b_y = 4.5. (a) Find the angle between the directions of $\stackrel{\to }{a}$ and $\stackrel{\to }{b}$. There are two vectors in the xy plane that are perpendicular to $\stackrel{\to }{a}$ and have a magnitude of 5.0 m. One, vector $\stackrel{\to }{c}$, has a positive x component and the other, vector $\stackrel{\to }{d}$, a negative x component. What are (b) the x component and (c) the y component of vector $\stackrel{\to }{c}$, and (d) the x component and (e) the y component of vector $\stackrel{\to }{d}$?
