Question: A person is running at 10 m/s on a moving walkway that moves at 2 m/s in the same direction. What is the person\'s speed relative to a stationary observer?

Options:

8 m/s
10 m/s
12 m/s
2 m/s

Correct Answer: 12 m/s

Solution:

The person\'s speed relative to a stationary observer is the sum of their speeds: 10 m/s + 2 m/s = 12 m/s.

Questions & Step-by-Step Solutions

A person is running at 10 m/s on a moving walkway that moves at 2 m/s in the same direction. What is the person's speed relative to a stationary observer?

Step 1: Identify the speed of the person running. The person is running at 10 m/s.
Step 2: Identify the speed of the moving walkway. The walkway moves at 2 m/s in the same direction.
Step 3: To find the person's speed relative to a stationary observer, add the speed of the person to the speed of the walkway.
Step 4: Perform the addition: 10 m/s (person's speed) + 2 m/s (walkway's speed) = 12 m/s.
Step 5: Conclude that the person's speed relative to a stationary observer is 12 m/s.
