In Fig. 3-31, a vector a with a magnitude of 17.0 m is

directed at angle θ = 56.0° counterclockwise from the + x axis.

What are the components (a) ax and (b) ay of the vector? A second

coordinate system is inclined by angle θ =  18.0° with respect

to the first. What are the components (c) ax  and (d) ay  in this

primed coordinate system?
