Physics problem- Newton Forces

<p>I have a tutor for physics that uses the SAT 2 physics book to help me. However, he gave me a practice problem that he found as a challenge. I want to understand the solution and its steps so can anyone please help me solve the problem?</p>

<p>"
A car rounds a banked curve with an banking angle θ. The radius of curvature of the road is "R" and the coefficient of static friction is µ.</p>

<p>A) What is the range of speeds that the car can have witout slipping up or down the road?
B) what is the minimum value of µ such that the minimum speed is zero?</p>

<p>THANK YOU</p>
