Relative to the ground, a car has a velocity of 22.6 m/s, directeddue north. Relative to this car, a truck has a velocity of 21.6 m/sdirected 48.0 ° south of east. Find the (a)magnitude and (b) direction of the truck'svelocity relative to the ground. Give the directional anglerelative to due east.

I was able to get the magnitude this problem in the book (18 m/s,22.8 m/s, 52.1d) but couldn't get the same tactics to work on thefirst number above.
