Answer to Question #133702 in Physics for J'Maalyah Rogers

Question

Two sisters had no displacement from there house after 2 hours, one sister was very tired after the two hours but the other one was not, why?

Answer 1

By definition, displacement is the shortest distance from the initial to the final position. Thus, the described situation is possible if one sister stays home all the time and the second one goes out, walks for 2 hours and return to the house. In both cases their displacements are equal to 0, but second sister get tired because whe was walking all 2 hours.
