assume each tick mark represents 1 cm. calculate the total displacement if a toy car starts at 0, moves 5 cm to the left, then 8 cm to the right, and then 3 cm to the left. the car moves cm, so there is no displacement.
Answer
Explanation:
Step1: Define left - right directions
Let left be negative and right be positive.
Step2: Calculate displacements
First displacement: $- 5$ cm (left). Second displacement: $+8$ cm (right). Third displacement: $-3$ cm (left).
Step3: Sum up displacements
Total displacement $=-5 + 8-3$ $=(-5-3)+8$ $=-8 + 8$ $=0$ cm
