Answer:
The displacement of 2 m south.
Explanation:
Given that,
A radio controlled car rolls 10 m south, then reverses direction and rolls 8 m north.
The car has traveled a distance of 18 m.
The displacement is the distance between the initial posit to final position.
The displacement will be
D= final position -initial position
D = +8-10
D = -2 m
Hence, The displacement of 2 m south.
