A car is at rest in a circle of radius r. The car then accelerates, but friction limits the speed to some max speed v. At what angle is the max speed v reached? (calculus is involved).
The key is to draw a detailed FBD, which I need help with. So far the forces I have are: centripital, component of friction pointing perpendicular to the radius, and another component of friction pointing towards the center of the circle.
Also, how to relate the angle to the FBD?
Thanks
