How do change the formula for momentum to calculate it with a coefficient of kinetic friction

I'm not sure what you're asking, can you be more specific? When a body feels a frictional force, to find the momentum you must first integrate the acceleration function to find velocity. If you're trying to do a specific problem, I would draw a free-body diagram.

$$p(1)+\int Fdt=p(2)$$
