Question

A rabbit runs 4.8 m across a yard, stops, then runs 2.5 m back in the opposite direction. What is the rabbit's displacement from the starting point?

a) 2.3 m
b) 7.3 m
c) -2.3 m
d) -7.3 m

Answer 1

The rabbit's displacement from the starting point is 2.3 m.

Step-by-step explanation:

The rabbit's displacement from the starting point is 2.3 m. To calculate the displacement, we take the difference between the rabbit's initial position and final position. The rabbit runs 4.8 m across the yard, so its initial position is at 0 m and its final position is at 4.8 m. Then, it runs 2.5 m back in the opposite direction, so its final position becomes 2.3 m.
