Question

Two cars moving in opposite directions cover same distance d in one hour. If the cars were moving in north-south direction, what will be their displacement in one hour?

Answer 1

Assuming the two cars are moving in the opposite directions from the same point Distance moved by each car in 1 h = d After 1 h, Displacement of the cars relative to each other Displacement of car 2 (moving north) relative to the initial position Displacement of car 1 (moving south) relative to the initial position = - d
