To find the frictional force acting on the sled, we can follow these steps:

1. Calculate the weight of the sled:

 

2. Calculate the net force acting on the sled:

Using Newton's second law:

 

Where:

 

So,

 

3. Identify the forces acting on the sled:

The forces acting on the sled are:

The horizontal component of the pulling force

The frictional force

 

4. Calculate the horizontal component of the pulling force:

The horizontal component of the pulling force is given by:
