Solving Vector Problems in Physics: Hot Air Balloon and Wind Velocity

Click For Summary

Homework Help Overview

The problem involves a hot air balloon being carried by wind, specifically examining the direction a flag held by a passenger will point due to the wind's influence. The subject area relates to vector analysis in physics, particularly in the context of motion and forces.

Discussion Character

  • Exploratory, Assumption checking

Approaches and Questions Raised

  • Participants discuss the relationship between the wind's velocity and the balloon's motion, questioning how the wind affects the flag's position. Some consider the intuitive aspects of motion in relation to the balloon's speed and direction.

Discussion Status

The discussion is ongoing, with various interpretations being explored regarding the flag's direction. Participants are questioning assumptions about the effects of wind and the relative motion of the balloon and the flag.

Contextual Notes

There is a lack of explicit information about the balloon's altitude or other environmental factors that might influence the flag's behavior. Participants are also considering the relevance of the passenger's perspective in relation to the wind's effect.

Homework Statement


A hot air balloon is carried by a wind with a velocity of 20 km/h [E]. If a passenger holds a flag out of the gondola, in what direction will the flag point?


Homework Equations





The Attempt at a Solution


The answer says down but idk why?
 
Physics news on Phys.org
I suppose the wind will carry the balloon along at the speed of the wind. Therefore the air surrounding the balloon will be moving at the same speed as the balloon.

Probably whatever direction the passenger wanted to point it.
 
Which way do flags hang when there is no wind?
 
Is the person traveling equivelocity relevant to the wind in the gondola? Imagine being in a convertible if that helps you picture it intuitively.
