Given information

The radius of curve =

The coefficient of static friction=  

Banked for design speed,  

 

Formula Used:

Banking of road:
 
Where,
design speed
the radius of the curve
acceleration due to gravity
Banking angle

Step-by-step explanation

Step 1.

First, we'll figure out the banking angle for a zero-friction bank at The normal force's vertical projection counteracts the gravitational force pressing on the automobile, while its horizontal projection acts as a centripetal force. As a result, we have

  

When we divide these two equations, we get
