Answer 1

Question : The worker covers a distance of 70 km from his house to his place of work and 40 km towards his house back. Then the displacement covered by the worker in his whole trip is

Given :

Distance covered from his home to work place = d1 = 70 km

Distance covered from his work place to house = d2 = 70 km

Expanation :

Displacement :  Displacement is calculated as the shortest distance between starting and final point which prefers straight-line path over curved paths. It gives the shortcut paths for the given original paths.

So here starting point is from home and also ending point is home.

So the displacement is zero.

So, The displacement covered by the worker in his whole trip is 0 .
