Physics

To find the coefficient of kinetic friction () between the car and the surface, follow these steps:

Step 1: Calculate the weight of the car

 

Step 2: Calculate the vertical component of the pulling force

 

Step 3: Calculate the normal force ()

The normal force is the weight of the car minus the vertical component of the pulling force:

 

Step 4: Calculate the net force acting on the car ()

Using Newton's second law:

 

Step 5: Calculate the horizontal component of the pulling force
