Question

A cyclist starts at a position of 0 m and takes 3 s to move east to a position of +8 m. He then cycles west to a position of +5 m which takes an additional 2 s.What is the cyclist’s displacement?a. +11mb. -8mc. -5m

d. +5m

Answer 1

The cyclist’s displacement is 5 meters.

Step-by-step explanation:

It is given that,

Initial position of the cyclist is at 0 meters i.e. at origin

The cyclist moves to east to a position of +8 m. East shows the positive x axis. He then cycles west to a position of +5 m which takes an additional 2 s. We know that the shortest path covered by the cyclist is called its net displacement.

Displacement = final position - initial position

Displacement = +5 m - 0 m

Displacement = +5 m

So, the cyclist’s displacement is +5 meters.
