Hello, I am really struggling with calculating the final rotation of a spinning wheel. I am not even sure if my equation for changing the velocity of the spinning wheel given a coefficient of friction is even correct so I will post it here...
change in angular velocity = angular velocity * friction * dT
Every frame I am setting a new angular velocity based on the above equation.
angular velocity = angular velocity - change in angular velocity
So in this universe where the above equation governs a spinning wheel, how would I find the final rotation of the wheel given an initial velocity (V1) and a coefficient of friction (0.185).
My attempt thus far:
Calculate the acceleration of the wheel (which I believe is the "change in angular velocity").
Then use that along with the initial speed and solve for Speed equals 0 (when the wheel finally stops). However, I think the problem I am having is I'm unfamiliar with the mathematics involved when the acceleration is constantly changing at every instant in time. I believe I have non constant acceleration because it depends on the current angular velocity to calculate the change in angular velocity.
Can someone give me a tip?
