4 Problem Consider two cars A and B moving at constant speeds VA = 60 kph and vB = 80 kph. Car A is traveling along a circular road that has radius r = 300 meters and is at an angle of 0 = 45 deg relative to car B. Car B is traveling westbound along a straight line. A VA UB A B Determine a symbolic expression for (a) the relative velocity vector vA/B using the unit vectors of a polar reference frame defined at point B, (b) the angular rate è, and (c) the radial rate r. Numerically evaluate your expressions for è and r. (Hint: Begin by expression both VA/O and VB/O in terms of polar frame unit vectors.)
