At the beginning of a 3.0-h plane trip, you are traveling due north at 192 km/h. At the end, you are traveling 250 km/h in the northwest direction (45° west of north).

Find the magnitude of the change in velocity.


Find the change in direction of your velocity. Enter the angle in degrees where negative indicates north of west and positive indicates south of west.


What is the magnitude of your average acceleration during the trip?
