Q1. A jogger starts at one corner of a rectangular park measuring 120 m by 80 m and walks once all the way around back to that same corner. What is the magnitude of its displacement for this complete round?
- A.240 m
- B.0 m
- C.200 m
- D.400 m
Answer: B. 0 m
A complete loop ends at the starting point, so the straight-line gap between start and finish is zero. Displacement = 0 m, while the distance covered equals the perimeter 2*(120 + 80) = 400 m.
Q2. After moving along every edge of a rectangular yard that is 90 m long and 70 m wide, A security guard ends the trip at the very corner it began from. What displacement has it undergone?
- A.180 m
- B.320 m
- C.160 m
- D.0 m
Answer: D. 0 m
A complete loop ends at the starting point, so the straight-line gap between start and finish is zero. Displacement = 0 m, while the distance covered equals the perimeter 2*(90 + 70) = 320 m.
Q3. A toy car completes a single full lap of a rectangular table top whose sides are 60 m and 40 m, finishing where it started. What is its net displacement over that lap?
- A.100 m
- B.200 m
- C.0 m
- D.120 m
Answer: C. 0 m
A complete loop ends at the starting point, so the straight-line gap between start and finish is zero. Displacement = 0 m, while the distance covered equals the perimeter 2*(60 + 40) = 200 m.
