Answer to Question #255828 in Mechanics | Relativity for Siddhi

Question

An object moves 60m due east and then 80 m due north find the distance travelled and the magnitude of displacement

Answer 1

The distance traveled is the sum of both distance, or

$$d=60+80=140\text{ m}.$$

The magnitude of displacement is

$$D=\sqrt{60^2+80^2}=100\text{ m}.$$
