he displacement of an airplane flying from San Francisco International Airport (SFO) to San Jose International (SJC) is 30 nautical miles, 36 south of east. Flying from SJC to Tracy, the plane's displacement is 36 nautical miles, 52 east of north. What is Tracy's position vector, if SFO is taken as the origin? (A nautical mile is slightly larger than a statute mile. Give you answer in nautical miles. All numbers are known to two significant figures.)
