Coefficient of Kinetic friction problem

1. The problem statement, all variables and given/known data
Harry pulls a sled with a mass of 110kg along a level surface of the forest in a straight line at a constant velocity. What is the coefficient of kinetic friction between the surface and the sled?

2. Relevant equations
$$f_k = \mu_k N$$
Fg=ma

3. The attempt at a solution
I calculated the downward force of the sled, which is 1079.1 N. After that I'm not really sure what to do. The other examples we did in class gave an angle, but this one doesn't seem to have one.
Thanks in advance

I would expect more information to be given with this.

Well, I asked my teacher and it was a typo on the worksheet. There is suppose to be more information. I solved it after I got the information. Thanks anyway.

Ahh, the old typo on the worksheet. I'm sure that frustrated more thana few students. At least its sorted now.
