Soham starts from his house, which is taken as the origin on a straight east–west road. He walks 120m due east to a bakery and then walks 70m due west towards his house.
(a) Calculate the total distance covered by Soham.
(b) Determine his net displacement from the origin. State clearly the magnitude and the direction.
(c) Compare the magnitude of the displacement obtained in part (b) with the distance calculated in part (a).
