Answer:
Subtraction operation
The car's displacement is 120 m west
Explanation:
Given;
first motion of the car as 150 m east
second motion of the car as 30 m west
The mathematical operation that will be used to determine the net movement of the car is subtraction operation.
The net movement of the car is the car's displacement.
Displacement is given by;
D = final position - initial position
D = 30 m - 150 m
D = - 120 m
The negative sign is direction = west ward direction
Thus, the car's displacement = 120 m west
