Given information

We are given that:

Mass of the snowboarder,     

Coefficient of kinetic friction on the inclination,       

Coefficient of kinetic friction on the flat surface,     

Length of the inclined plane,     

Initial velocity of the snowboarder, .   

Angle of inclined plane from the horizontal,    

 

Step-by-step explanation

Step 1.

From the third equation of motion we get that:

 

Where, represents the final velocity of the snowboarder,  is the initial velocity, is the acceleration and is the displacement.

The free body diagram is as shown below:
