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

In summary, when a hot air balloon is carried by a wind with a velocity of 20 km/h [E], the air surrounding the balloon will also move at the same speed. If a passenger holds a flag out of the gondola, the flag will point in the direction the passenger chooses, regardless of the wind's direction. When there is no wind, flags will hang downwards. The person traveling in the gondola is moving at the same speed as the wind, similar to a person in a convertible.

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.
 
  • #4
Which way do flags hang when there is no wind?
 
  • #5
Is the person traveling equivelocity relevant to the wind in the gondola? Imagine being in a convertible if that helps you picture it intuitively.
 

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

What are vectors in Physics 11?

Vectors in Physics 11 are quantities that have both magnitude and direction. They are represented by arrows, with the length of the arrow representing the magnitude and the direction of the arrow representing the direction.

How do I add vectors in Physics 11?

To add vectors in Physics 11, you must first resolve them into their horizontal and vertical components. Then, you can add the horizontal components together and the vertical components together. The resulting vectors will be the sum of the original vectors.

What is the difference between a scalar and a vector?

A scalar is a quantity that has only magnitude, while a vector has both magnitude and direction. Examples of scalars include temperature, mass, and speed, while examples of vectors include displacement, velocity, and force.

How do I calculate the magnitude of a vector?

The magnitude of a vector can be calculated using the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides. In the case of a vector, the magnitude is equal to the square root of the sum of the squares of its horizontal and vertical components.

What is the difference between position and displacement?

Position refers to the location of an object in space, while displacement refers to the change in position of an object. Position is a scalar quantity, while displacement is a vector quantity.
