Question

A person walks 4 meters east in 2 second, then walks 3 meters west in 1 second. Determine average speed and average velocity.

Answer 1

Solution

Distance = 4 meters + 3 meters = 7 meters

Displacement = meters, to northeast.

Time elapsed = 2 second + 1 second = 3 seconds.

Average speed = distance / time elapsed = 7 meters / 3 seconds = 4 meters/second
