Question

10. A person walks 12.0 m east, then turns and goes 5.00 m west, then turns and goes back 2.00 m east.

Answer 1

Step-by-step explanation:

Given that,

A person walks 12.0 m east, then turns and goes 5.00 m west, then turns and goes back 2.00 m east.

(a) Distance is equal to total path covered during the entire journey.

Distance = 12 + 5 +2

Distance = 19 m

(b) The shortest path covered is equal to the shortest path traveled. Let east is positive and west is negative. So,

Displacement = 12 +(-5) +2

Displacement = 9 m
