How Far Does an Object Travel with Given Friction and Initial Velocity?

[mmiller9913]

Homework Statement

An object is given a push along a surface of which the coefficient of kinetic friction is .20. The initial velocity is 4m/s. How far does it go before it stops.

Homework Equations

Fnet=ma
Ff=U(Fn)

The Attempt at a Solution

Is it just me or do you have to know the mass to figure out this problem? I honestly can not seem to get a start on it.

In lieu of energy methods, if you use your relevant equations, Fnet =ma , where Fnet is U(Fn), and Fn is___?, you may find that you can get the acceleratiion without knowing the mass. Then get the distance traveled using the kinematic equations of motion.
