of 83 km/h? John drives 18 km directly west from Orion to Chester at a speed of 83 km/h, then directly south for 9.0 km to Seiling at a speed of 89 km/h, then finally 38 km southeast to Oakwood at a speed of 97 km/h. Assume he travels at constant velocity during each of the three segments.
(a) What was the change in velocity during this trip? [Hint: Do not assume he starts from rest and stops at the end.]
magnitude km/h
direction ° south of east
(b) What was the average acceleration during this trip?
magnitude km/h2
direction ° south of east
