6. A 1200 kg car rounds a curve of radius 66 m banked at an angle of 14°. What is the magnitude of the friction force required for the car to travel at 82 km/h?


Expert Answer

Step 1

The free body diagram of situation is,

Step 2

The force exerted on the car in the x direction is,

Step 3

Here, N is the normal force, f is the frictional force, θ is the banking angle, m is the mass, v is the speed of the car, r is the radius of the curve and mv2...
