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 = 2.00 min,
and then drives northwest at
v3 = 30.0 m/s
for
t3 = 1.00 min.
For this 6.00-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.)

(b)
average speed (in m/s)

(c)
average velocity (Enter the magnitude in m/s and the direction in degrees south of west.)
