- Homework Statement
- I've been trying to calculate the rotational inertia of this rotating gondola on this ride at this theme park.

However, they do not directly give me a specific formula to use-because with different objects, there are different formulae that you use to determine the rotational inertia of an object

mass of gondola = 6 tonne (6000kg)

radius = 3m

I will attach a picture of what it looks like

- Relevant Equations
- I have attached a picture of different possible formulae's

**Picture of gondola:**

**Formulae:**

Initially, I used the equation: I=mr^2

I=(6000)x(3)^2

T=54,000kgm^2

(but apparently this is incorrect)

So, basically, I don't know which formula would suit best for the gondola (the picture above). I would consider the gondola a hollow object as the mass is concentrated on the outer edges.
