Balloon Accel: Find 16.4 m/s^2

In summary, the conversation is about finding the acceleration of a balloon filled with helium, given its mass, volume, and the constant density of air. The solution involves using the equations for buoyant force and net force, and the answer was found to be 3.45 m/s^2. The answer key provided a different answer, but it was deemed incorrect.

Homework Statement


The mass of an empty balloon is 0.41 kg it got inflated with 0.0938 kg of helium which ressulted in his volume being 0.524 m^3 after being inflated then left to ascend considering the air's density is constant and is 1.30 kg/m^3 what is the acceleration of the balloon (dont consider air resistance)[/B]

Homework Equations


Fb=density*volume*g
Fg=mg
Fnet
a=Fnet/m

The Attempt at a Solution


Fb=1.30*0.524*9.81=6.68257N
Fg=(0.41+0.0938)9.81=4.94N
6.68-4.94=1.74N
1.74/(0.41+0.0938)=3.45 m/s^2
Tye answer sheet says its 16.4?[/B]

1. What is "Balloon Accel"?

"Balloon Accel" is a scientific term used to describe the acceleration of a balloon. It refers to the change in velocity of the balloon over time.

2. How is the acceleration of a balloon measured?

The acceleration of a balloon can be measured by using a formula that takes into account the distance the balloon moves and the time it takes to travel that distance.

3. What is the significance of finding an acceleration of 16.4 m/s^2?

An acceleration of 16.4 m/s^2 is considered to be a high acceleration value. It means that the balloon is changing its velocity at a rapid rate, indicating a significant force acting on it.

4. How is the acceleration of a balloon affected by different factors?

The acceleration of a balloon can be affected by factors such as the size and weight of the balloon, the amount of air inside the balloon, and any external forces acting on the balloon (such as wind or gravity).

5. Why is it important to study the acceleration of balloons?

Studying the acceleration of balloons can provide insights into the physical properties of balloons and how they interact with their environment. It can also help in the development of new technologies and applications involving balloons, such as weather balloons or hot air balloons.
