Trying to find how much work is done by friction
1. The problem statement, all variables and given/known data
A man drags a table 4.05 m across the floor, exerting a constant force of 51.0 N, directed 25.0° above the horizontal.
How much work is done by friction? Assume the table's velocity is constant.
2. Relevant equations
3. The attempt at a solution
I dont understand how I am supposed to find the coefficient of friction without knowing what the mass is.

The Force and distance need to be parallel and that is where the 25'deg angle comes into play.
No need for mass, as people are fat enough.
