We are given that:

Mass of the ice skater .  

Distance .  

Final velocity .  

Coefficient of kinetic friction   .   

Step-by-step explanation

Step 1.

The work-energy theorem states that the work done is equal to the change in kinetic energy. 

 

Where, is the final velocity, is the initial velocity.

The frictional force is given by:

.  

where is the normal force.
