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?

  3. 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
