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? A. 0.2 m/s west B. 0.2 m/s east C. 1.1 m/s west D. 0.9 m/s east

Answer 1

B or .2 East is the correct answer

Answer 2

The correct answer is option B.

Step-by-step explanation:

Velocity of the walkway =
`v_w=0.9 m/s`

velocity of the man =
`v_m=1.1m/s`

Relative velocity of the man with respect to moving walkway =
`v_r`

`v_r=v_m-v_w=1.1 m/s-0.9 m/s=0.2 m/s`

The relative speed of man with respect to the velocity of walkway is 0.2 m/s towards east direction.
