If a curve with a radius of 88m is perfectly banked for a car traveling 75km/h, what must be the coefficient of static friction for a car not to skid when traveling at 95km/h? ac=v^2/r

PLEASE HELP D:

Using the equation you've provided, you can get two different values for centripetal acceleration. The first at 75km/h, the second at 95km/h. Did the problem provide the mass of the car? If not, I guess you could just generally represent it with m to find out the force required.

In other words, force times the difference in acceleration.

I'm sorry, that's *mass* times the difference in acceleration for force.
