Kinematics / Forces Friction Problem?

[whoopie88]

Homework Statement

A baseball player slides into third base with an initial speed of 7.00 m/s. If the coefficient of kinetic friction between the player and the ground is 0.37, how far does the player slide before coming to rest?

The Attempt at a Solution

I'm not really sure how to start this problem; there doesn't seem to be enough information given. If the coefficient of friction is given, I feel like I should know what the Normal Force is, but I don't have the mass or the weight of the player, so I'm kind of lost as to how I should start this.

Help?

Call the mass 'm' and continue. Maybe you won't need the actual value.
