Question

A boy runs 30 m east, 40 m north, 50 m west. what is his net displacement?

Answer 1

I believe the answer to be 44.72m

Answer 2

Net displacement, d = 44.72 meters

Step-by-step explanation:

In the attached figure, OA shows the net displacement.

Distance 1, d₁ = 30 m

Distance 2, d₂ = 40 m

Distance 3, d₃ = 50 m

Displacement of an object is equal to the shortest distance covered by an object. Here, the net displacement of the person can be calculated as :

`d=√((50-30)^2+40^2)`

d = 44.72 meters

So, the net displacement of the boy is 44.72 meters. Hence, this is the required solution.
