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.   Want an answer?  No answer yet. Submit this
