- Homework Statement
- When we stop rotating the flywheel, the rotational frequency drops in 5 minutes to two thirds of its starting frequency, in which time the flywheel does 800 rotations. What is the starting frequency?

- Relevant Equations
- None given

I converted 5 minutes to 300 seconds, and movement angle per second as shown on the picture. From here on I am lost, as the angular velocity can't be calculated, as the time given isn't the one in which the flywheel does one rotation.

I apologise if I used any expressions wrong, english is not my mother toungue...
