Relative Velocity moving sidewalk

In summary, the conversation is about a moving sidewalk at an airport and a person walking on it at different speeds. The question asks for the time it takes for the person to reach the opposite end if they walk in the same direction or opposite direction as the sidewalk. The formula for calculating duration using distance and speed could potentially be used to solve this problem.

Homework Statement


A "moving sidewalk" at an airport moves at 1.5m/s and is 12 m long. A person enters the sidewalk and walks at 1.8 m/s relative to the sidewalk.
A)How much time is required for the person to reach the opposite end if the person walks in the same direction as the sidewalk is moving?
B) How much time is required for the person to reach the opposite end if the person walks in the opposite direction?The attempt at a solution
Sorry! My professor didn't really explain how to do this so I'm stuck on this problem. Thanks!

Make an attempt.
What formulae might you be able to use, if you're calculating duration, given distance and speed?
 

Related to Relative Velocity moving sidewalk

1. What is relative velocity on a moving sidewalk?

Relative velocity on a moving sidewalk refers to the speed and direction of an object as it moves in relation to the moving sidewalk. It is a combination of the object's own velocity and the velocity of the moving sidewalk.

2. How does relative velocity affect my movement on a moving sidewalk?

Relative velocity on a moving sidewalk can either increase or decrease your overall velocity, depending on the direction of the moving sidewalk and your own velocity. If you are moving in the same direction as the moving sidewalk, your relative velocity will increase, but if you are moving in the opposite direction, your relative velocity will decrease.

3. Is relative velocity the same as absolute velocity on a moving sidewalk?

No, relative velocity and absolute velocity on a moving sidewalk are not the same. Absolute velocity refers to the speed and direction of an object in relation to a fixed reference point, while relative velocity takes into account the movement of the object in relation to another moving object or surface.

4. How do you calculate relative velocity on a moving sidewalk?

To calculate relative velocity on a moving sidewalk, you need to first determine your own velocity and the velocity of the moving sidewalk. Then, use the formula vrel = vobj + vms, where vrel is the relative velocity, vobj is the object's velocity, and vms is the velocity of the moving sidewalk.

5. Can relative velocity on a moving sidewalk be negative?

Yes, relative velocity on a moving sidewalk can be negative if the object is moving in the opposite direction of the moving sidewalk. This means that the object's overall velocity is decreasing due to the opposite movement of the moving sidewalk.
