Question

2. A nutty professor leaves a history classroom and walks 10. meters north to a drinking fountain. Then, in a daze, she turns and walks 30. meters south to an art classroom. (draw vectors to scale to show your work)

(a) What is the professor’s total displacement from the classroom to the art classroom?
(b) What was the total distance she traveled?

Answer 1

• 
  `\vec{N}=10m`
• 
  `\vec{S}=30m`

Total displacement:-

`\\ \sf\Rrightarrow 10-30=20m`

Total distance

`\\ \sf\Rrightarrow 10+30=40m`
