Question
A force of 300 N is sufficient to keep a 100 kg crate moving at a constant speed across a wooden floor. What is the coefficient of sliding floor?

The vertical force on the floor is M*g = 980 N
Uk*980 = 300 (since there is no acceleration)
Uk = 300/980 = 0.306
is the kinetic friction coefficient
Uk*980 = 300 (since there is no acceleration)
Uk = 300/980 = 0.306
is the kinetic friction coefficient
