Baseball player slide Friction problems

[triplezero24]

Heres what the book gives:

A baseball player slides into third base with an initial speed of 7.90m/s. If the coefficient of kinetic friction between the player and the ground is 0.41, how far does the player slide before coming to rest.

Help? Please?

Force of friction*t = mvf - mvi

Force of friction = uk*normal force

 

[Alkatran]

Or, more wordily:

The coefficient of friction is how much of the normal force, the force the ground applies on you (usually equal and opposite to the force of gravity). A coefficent of .5 means the force of friction is 50% of the normal force.
