Question

I need help with question 8 it is about distance and displacement

Answer 1

Distance = 9 km

Displacement = 9 km east

Explanation:

When we speak of distance we refer to the length between any two points in space, while displacement refers to the distance from an initial position to a final position regardless of the path.

In this case, being in the same direction, the displacement and distance are the same (in magnitude).

Therefore:

`\begin{gathered} \text{ distance = 5 km + 4 km = 9 km} \\ \text{displacement = (5 km + 4 km) - 0 km = 9 km direction east } \end{gathered}`
