- Homework Statement
- A dial can spin on a fixed rotational axis. The mass of the dial is m. On the right side of the dial is a little box also with the mass m, but on the left side of the dial there is a little box with a mass of 1/2 m. The gravity of the earth pulls of course harder on the right side of the dial, so when the dial is released it starts turning clockwise. The moment of inertia is Id=1/2mR², where R is the radius of the dial.

- Relevant Equations
- a) what is the angular velocity of the dial just after it has been released?

b) Use conservation of energy to find the angular velocity of the system when the heavier mass is at the lowest point and the lighter on at the highest point.

c) What is the angular velocity of the system in the same state as in b)?

What I have done is on my Ipad that I cant upload or at least don't know how to... :/
