Rotating Flywheel: Tips & Tricks for Beginners

[Bolter]

Homework Statement

Working out torque from rotating flywheel

Relevant Equations

Rotational equivalent of SUVAT equations
Torque = moment of inertia * angular acceleration

Hey everyone!

Was trying to answer this question and was wondering if this was the right way to go about it?

Any help would be really appreciated!

Sounds good.

Just remember to include units (I know it's a pain but as a "pseudo-physicist" I had to point it out.). Usually, including units throughout the entire problem is a good way to check if the solution is correct. If the units cancel out as desired, then your solution should be correct (unless you made some silly arithmetic mistake).

Ok thanks, I'll try to do that more often until it becomes second nature. It's not that I don't want to add units but always forget to

Yeah... I feel you. You'll get used to it after a while.
