Constant horizontal force and friction

[rasen58]

Homework Statement

A 50 kg is pushed across a floor by a constant horizontal force of 200 N. What is the force of friction?

Homework Equations

Ffr = coeff*Fn

The Attempt at a Solution

I'm not sure how to find it as I don't know the coefficient.
The answer says the answer is 200 N, but I don't know why it's equal to the applied force. The problem didn't say it was being moved at a constant velocity, it only has a constant applied force.

Check the problem statement for any other information. You feel it's incomplete as it stands, and it is incomplete as it stands.

Is the problem written correctly and completely or is there some missing parts !??

That's all that was given. I guess whoever wrote the problem wrote it incompletely.

Solve it for the coefficient of friction necessary for constant velocity, and include an explanation that you're making an assumption based on the given answer.
