Answer 2

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 will be

D=  final position -initial position

D = +8-10

D = -2 m

Hence, The displacement of 2 m south.
