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

Respuesta :

B or .2 East is the correct answer

Answer:

The correct answer is option B.

Explanation:

Velocity of the walkway =[tex]v_w=0.9 m/s[/tex]

velocity of the man = [tex]v_m=1.1m/s[/tex]

Relative velocity of the man with respect to moving walkway = [tex]v_r[/tex]

[tex]v_r=v_m-v_w=1.1 m/s-0.9 m/s=0.2 m/s[/tex]

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