Answer to Question #239807 in Physics for Morgan Hopkin

Question

Celia walks from her home to a position 2.8 km [W] of her home then to a position 6.7 km [E] of her home.

Determine Celia's total displacement. include units

Answer 1

Let's place the home in the origin. Then the total displacement is given as the distance between the start (origin) and end point (6.7 km [E]) of journey. The distance between the origin and 6.7 km [E] is

$$d = 6.7km$$

Thus, the displacement is 6.7 km [E].

Answer. 6.7 km [E].
