Question

A motorist drives south at 28.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.60 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.60 min trip, find the following values.
Let the positive x axis point east.
(a) total vector displacement in meter (magnitude) and degrees south of west.
(b) average speed in m/s
(c) average velocity in m/s (magnitude) and degrees south of west
