Question

In topic, equasions of motion.

Problem: a person travels east and 8m to north again travelled 16m to south .what is the displacement?

Answer 1

In the question no information is given about the eastward displacement of the man. So, we shall consider only the north and the south displacement.

Displacement towards north is = 8 m

Displacement towards south is = 16 m

Since, north and south are oppositely directed, so, the net displacement is = 16 – 8 = 8 m towards south.
