Question

A kayaker moves 22 meters northward, then 18 meters southward , and finally 24 meters northward what is the distance and magnitude and direction?

Answer 1

Distance = 64 metres

Displacement = 28 metres

Direction = northward

Step-by-step explanation:

Given that a kayaker moves 22 meters northward, then 18 meters southward , and finally 24 meters northward

Distance covered is only about the magnitude of the length covered.

Distance = 22 + 18 + 24 = 64 metres

The direction will be considered when calculating the displacement

Let northward be positive and southward be negative

Displacement = 22 - 18 + 24 = 28 metres

Since the displacement is positive, the direction of the motion is northward.
