Two forces, 473 N at 11 degrees and 423 N at 28 degrees are applied to a car in an effort to accelerate it.
a) What is the magnitude of the resultant of these two forces?
b) Find the direction of the resultant force (in relation to forward, with counter-clockwise considered positive). Answer in degrees from the positive x-axis, with counter-clockwise positive, within the limits of -180 to 180.
