Question

A bus driver heads south with a steady speed of v1 = 20.0 m/s for t1 = 3.00 min, then makes a right turn and travels at v2 = 25.0 m/s for t2 = 2.60 min, and then drives northwest at v3 = 30.0 m/s for t3 = 1.00 min. For this 6.60-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 = ? And direction =? (b) average speed (in m/s) (c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.) magnitude = ? And direction =?

(a) total vector displacement (Enter the magnitude in m and the direction in degrees south of west.)
magnitude = ? And direction =?
(b) average speed (in m/s)
(c) average velocity (Enter the magnitude in m/s and the direction in degrees south of west.)
magnitude = ? And direction =?
