Question

30 m
a path goes:
200 m up
200 m
30 m down
what is the displacement from the
star to the flags?
200 m
170 m up
170 m down
230 m

Explanation:

Step1: Understand Displacement

Displacement is net change in position. Let upward be positive, downward be negative.

Step2: Calculate Net Displacement

Initial move: \( +200\,\text{m} \) (up), then \( -30\,\text{m} \) (down).
Net displacement: \( 200 - 30 = 170\,\text{m} \) (up, since positive).

Answer:

170 m up (the option with "170 m up")
