Once a 15 kg crate is in motion on a horizontal ﬂoor, a horizontal force of 51 N keeps the crate moving with a constant velocity.

The acceleration of gravity is 9.81 m/s What is µk, the coeﬃcient of kinetic friction, between the crate and the ﬂoor?

51 N/(M*g) = 0.347

Drwls is wrong

Mass = 15kg
Ff= 51N
A= 9.81
Formula fg=m g, fg = 15 x 9.81, fg = 147.15
Next step, Ff = uFn, 51 = 147.15u, u= 0.3465
