Answer to Question #39202 in Mechanics | Relativity for Segun Akowonjo
Question #39202
A motorist drives south at 28.0 m/s for 3.00 min, then turns west and travels at 25.0 m/s for 2.40 min, and finally travels northwest at 30.0 m/s for 1.00 min. For this 6.40 min trip, find the following values. Let the positive x axis point east.
(a) total vector displacement
m (magnitude) ° south of west
(b) average speed
m/s
(c) average velocity
m/s (magnitude) ° south of west
