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

[roxxyroxx]

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?

 

[Delphi51]

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.

If a passenger holds a flag out of the gondola, in what direction will the flag point?

Probably whatever direction the passenger wanted to point it.

 

[Delphi51]

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.
