What is the mass of the box?

A box is given a push so that it slides across the floor. How far will it go, given that the coefficient of kinetic friction is 0.23 and the push imparts an initial speed of 3.9 m/s?
Could someone help, to me it is missing a part but that is the entire question

Something is missing. What is the mass of the box? You need this in order to calculate the deaccelation of the box. Then you multiply the kinetic coefficient by the mass of the box. This will give you the force acting against the motion of the box. Then use "F=ma" to calculate that deaccelation. I hope this helps you.

Nothing is missing. The mass cancels. Acceleration = -0.23g
