Question

A car starting at position 16m travels out to position 67m and turns around and speeds back to position 16m. What was the displacement of the car?

A 0m

B 16m

C 67m

D 102m

Answer 1

Answer: D. 102m

Explanation: Because if you subtract 67m-16m=51. 51 +51 is 102m

Answer 2

Displacement, D = 0

Step-by-step explanation:

The initial position of the car is at 16 m. It travels out to position 67 m and turns around and speeds back to position 16 m. Finally, it reaches to a position of 16 m.

We know that the displacement of an object is equal to the shortest path covered by it.

Displacement = final position -initial position

D = 16 m - 16 m

D = 0

So, the displacement of the car during the entire journey is 0. Hence, this is the required solution.
