Respuesta :
The displacement covered by the worker in the whole trip is 30km.
The easiest way to solve this problem is using the displacement equation:
Δx = x₂ - x₁
A worker covers a distance of 40 km from his house to his place of
work, and 10 km towards his house back. So:
Δx = x₂ - x₁ = 40km - 10km = 30km
Since displacement is a vector quantity, the displacement of the worker from the data is 30Km.
What is displacement?
Displacement refers to distance covered in a specific direction. Hence, unlike distance, we include direction in our discussion of displacement.
As such, displacement is a vector quantity therefore, the displacement of the worker is obtained from 40 Km - 10 Km = 30Km.
