Question

An orienteer runs north at 5 m/s for 120 seconds, and then west at 4 m/s for 180 seconds. Provide a graphic solution to show the orienteer's resultant displacement.

Answer 1

Answer:937.22 m

Step-by-step explanation:

Given

First orienteer is running towards North with 5 m/s for 120 s

so he covers a distance of
`5* 120=600 m`

After that He runs towards west at 4 m/s for 180 s

So he covers a distance of
`4* 180=720 m`

Mathematically its net Displacement is

displacement
`=√(600^2+720^2)`

displacement
`=937.22 m`
