A 20.0-kg crate, starting from rest, is pulled across a floor with a constant horizontal force F. for the first 9.00 m the floor is frictionless, and for the next 12.0 m the coefficient of friction is 0.200. The final speed of the crate after being pulled these 21.0 m is 18.0 m/s. How much is the constant horizontal force F mentioned above?
