Question: A person is running at 3 m/s on a moving escalator that moves at 2 m/s in the same direction. What is the speed of the person relative to a stationary observer?

Options:

1 m/s
3 m/s
5 m/s
2 m/s

Correct Answer: 5 m/s

Solution:

Speed of person relative to observer = Speed of escalator + Speed of person = 2 m/s + 3 m/s = 5 m/s.

Questions & Step-by-Step Solutions

A person is running at 3 m/s on a moving escalator that moves at 2 m/s in the same direction. What is the speed of the person relative to a stationary observer?

Step 1: Identify the speed of the person running. The person is running at 3 m/s.
Step 2: Identify the speed of the escalator. The escalator is moving at 2 m/s in the same direction.
Step 3: To find the speed of the person relative to a stationary observer, add the speed of the person to the speed of the escalator.
Step 4: Perform the addition: 3 m/s (person) + 2 m/s (escalator) = 5 m/s.
Step 5: The final result is that the speed of the person relative to a stationary observer is 5 m/s.
