Question

John drives 16.0 km directly west from Orion to Chester at a speed of 88.0 km/h, and then directly south for 8.00 km to Seiling at a speed of 80.0 km/h, and then finally 34.0 km southeast to Oakwood at a speed of 100 km/h. Assume that he travels at a constant velocity during each of the three segments.

What was the change in magnitude of velocity during this trip? (Hint: Do not assume that he starts from rest and stops at the end.)


__________ km/h

Answer 1

Explanation: | John | 88 | 80 | 100

---|--------|-----|-----|------

Orion | 0 | 0 | 0 | 0

Chester | 0 | 16 | 0 | 0

Seiling | 0 | 0 | 8 | 0

Oakwood | 0 | 34 | 0 | 0

Change in magnitude of velocity = 34 - 0 = 34 km/h
