Question: A plane flies 461 km east from city A to city B in 40.0 min and then 991 km south from city B to city C in 1.70 h. For the total trip, what are the
(a) magnitude and
(b) direction of the plane's displacement, the
(c) magnitude and
(d) direction of its average velocity, and
(e) its average speed?
Give your angles as positive or negative values of magnitude less than 180 degrees, measured from the +x direction (east).
