Question 1
A person walks 24 m North, then 21 m North, then 25 m North, then 16 m West. Find his displacement from the starting point.
Step-by-step:
1. Track net displacement:
- North-South: 70 m North
- East-West: -16 m West
2. Displacement = √(-16² + 70²) = √5156 = 72 m
3. Total distance walked = 86 m
