A curve in a speed track has a radius of $1,160\mathrm{ft}$ and a rated speed of $90\mathrm{mi}/\mathrm{h}$. (Rated speed is speed at which no friction is needed to кeep car on road - see hint). Knowing that a racing car starts skidding on the curve when traveling at a speed of $165\mathrm{mi}/\mathrm{h}$, determine he coefficient of static friction between the tires and the track under the prevailing conditions. (hint, you will need to find the oanking angle in order to find the friction coefficient).
