A chauffeur heads south with a steady speed of v, - 22.0 m/s for t, - 3.00 min, then makes a right turn and travels at v, - 25.0 m/s for ty- 2.20 min, and then drives northwest at v, 30.0 m/s for t, 1.00 min. For this 6.20-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 (b) average speed (in m/s) m/s M south of west (c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.) m/s magnitude direction south of west
