How to solve/ work this problem? If a curve with a radius of 88m is perfectly banked for a car traveling 75 km/h, what must be the coefficient of static friction for a car not to skid when traveling at 95km/h?
This is similar to a problem I answered Sunday.
In this case you have to use friction to avoid slipping away from the center of the turn, not towards it. There sill be a sign change.
See if you can figure it out. I have to get some sleep.
I get what you were doing, but I still need help on how to work this one, like step by step.
