Question

2. An ant starts at 2.1 m and moves 1.8 m left, 2.5 m right, 1.1 m left, and 1.4 m right. If the positive x-axis is to the

right, then what is the ant's total displacement?
O a) 1.0 m
Ob) 6.8 m
O c) 6.0 m
O d) 8.9 m
O e) -0.4 m

Answer 1

a) 1.0 m

Step-by-step explanation:

Displacement is the distance from point of origin to end point.

2.1 - 1.8 + 2.5 - 1.1 + 1.4 = 3.1 from 0

3.1 - 2.1 = 1.0 m from point of origin at 2.1

final answer: displacement = 1.0 m
