Problem: Find the following for path B in the figure:
(a) The distance traveled.
(b) The magnitude of the displacement from start to finish.
(c) The displacement from start to finish.
Solution:
Part A
Based on the figure, B travels from 12 to 7. The distance traveled is 5 meters.
Part B
The magnitude of the displacement is 5 meters.
Part C
The displacement is calculated keeping in mind the sign. The motion started at 12 and ended at 7. Therefore, the displacement is
