Question

A moving walkway has a speed of 0.9 m/s to the east. A stationary observer

sees a man walking on the walkway with a velocity of 1.1 m/s to the east.
What is the man's velocity relative to the moving walkway?

Answer 1

The man's velocity relative to the moving walkway is, v₂₃ = 0.2 m/s

Step-by-step explanation:

Given data,

The speed of the moving walkway, v₁₂ = 0.9 m/s

The speed of the man walking on a walkway to the stationary observer, v₁₃ = 1.1 m/s

The speed of the man walking on a walkway to the walkway, v₂₃ = ?

The formula for relative velocity is,

v₁₃ = v₁₂ + v₂₃

∴ v₂₃ = v₁₃ - v₁₂

Substituting the values,

v₂₃ = 1.1 - 0.9

= 0.2 m/s

Hence, the man's velocity relative to the moving walkway is, v₂₃ = 0.2 m/s
