Answer #1

The free-body diagram for the car is drawn below.

The normal force, N, has been resolved into horizontal and vertical components. and the banking angle,

Given, velocity of car , v = 46 m/s

In Vertical direction, acceleration = 0 ,therefore

Now consider the horizontal direction,

   (Substituting value of N )
