A chauffeur heads south with a steady speed of v1 = 22.0 m/s for t1 = 3.00 min, then makes a right turn and travels at v2 = 25.0 m/s for t2 = 3.00 min, and then drives northwest at vz = 30.0 m/s for tz = 1.00 min. For this 7.00-min trip, calculate the following. Assume +x is in the eastward direction. 

(a) total vector displacement (Enter the magnitude in m and the direction in degrees south of west.) 

magnitude 

direction • south of west m 

(b) average speed (in m/s) m/s 

(c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.) 

magnitude m/s 

direction • south of west
