  1. Question 1

    Q1. A girl walks 10m towards the West, then turns right and walks 5m. She then turns right and walks 10m. What is her net displacement?

    • A) 5m North
    • B) 5m South
    • C) 10m East
    • D) 5m East

    Answer: 5m South

    Explanation: 10m West, 5m North, 10m East. The West and East walks cancel out, leaving 5m North, but since she walked 10m East, the correct analysis shows she ends up 5m South of the starting latitude is incorrect, the correct is 5m North.
