Car B is rounding the curve with a constant speed of 54 km / h, and car A is approaching car B in the intersection with a constant speed of 72 km / h. Determine the velocity which car A appears to have to an observer riding in and turning with car B. The x-y axes are attached to car B. Is this apparent velocity the negative of the velocity which B appears to have to a nonrotating observer in car A? The distance separating the two cars at the instant depicted is 40 m.
