question 10 of 10
a man stands still on a moving walkway that is going at a speed of 0.3 m/s to the south. what is the velocity of the man according to a stationary observer?
a. 0.3 m/s north
b. 0.3 m/s west
c. 0.3 m/s east
d. 0.3 m/s south

Explanation:

Step1: Analyze relative motion

The man is standing still on the moving walk - way. His velocity relative to the walk - way is 0 m/s. The walk - way is moving at a speed of 0.3 m/s to the south.

Step2: Determine man's velocity for stationary observer

For a stationary observer, the man's velocity is the same as the velocity of the walk - way.

Answer:

D. 0.3 m/s south
