If the coefficient of kinetic friction between a crate and the floor is 0.20, then the fore needed to slide a 92 kg crate uniformly across the floor would be 180.504 N
Friction is a type of force that resists or prevents the relative motion of two physical objects when their surfaces come in contact.
The friction force prevents any two surfaces of objects from easily sliding over each other or slipping across one another. It depends upon the force applied to the object.
As given in the problem If the coefficient of kinetic friction between a crate and the floor is 0.20
The force needed = μN
where μ is the coefficient of the kinetic friction
μ =0.2
N is the normal force
N = mg
N = 92×9.81 N
Force needed to slide = 0.20× 92×9.81
=180.504 N
Thus, The force needed to slide a 92 kg crate uniformly across the floor would be 180.504 N
