Read Question Below!
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 = 3.00 min, and then drives northwest at v3= 30.0 m/s for t3 = 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.)
direction: _______ ° south of west_
(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.)
direction: _______° south of west
