I will assume that the box is moving at a constant speed, so that the frictional force is 70 N. Frictional force is defined as F = mu(the greek letter) times the normal force(in this case, mg). We can figure the normal force to be 9.8 times the 58 kg, which is 568.4 Newtons. So now, we need to figure mu, and to do so, we divide the 70 newton force by the normal force. mu = .123.

How does the roughness of surfaces that are toughing affect the friction between the surfaces?
The rougher a surface is, the higher the coefficient of static and kinetic friction will be.
Which coefficient of friction is greater static or kinetic?
static usully greater then kinetic
A horizontal force of 40 newtons will just start a 600 newton empty sled moving across packed snow what is the coefficients of static and kinetic friction?
static friction= normal contact force*coefficient of static friction 40 = (600*9.8) * CSF CSF=40/(600*9.8) (you can calculate that yourself, i cant be bothered) there isn't enough info to work out the coefficient of kinetic friction
What is coeffitient of stactic n kinetic friction?
The coefficient of static or kinetic friction depends on the surfaces that are causing friction. The formula for it is: force of friction over normal force.
Give an example of friction?
Case 2: A truck is travelling at a constant speed up a hill with a normal force of 1360N. The Force of the Kinetic friction acting on the truck is 266N. What is the coefficient of kinetic friction between the truck and the road? N = 1360N, Fk = 266N Step 1: Substitute the values in the below Kinetic Friction Coefficient formula: This example will guide you to calculate the Kinetic Friction Coefficient manually.
What factors can effect the amount of friction between two objects?
The force of friction between two objects is the product of the normal force and the coefficient of friction. The normal force is the component of force that is perpendicular to the plane of friction. For example, if you are pushing on a block of wood on the floor with a force F at an angle of 30 degrees above the horizontal, then the normal force N = F sin 30. The coefficient of friction is specific to the two materials, in this example the block of wood and the floor. In addition, there is a static coefficient of friction (applicable to a stationary situation) and a kinetic coefficient of friction (applicable when the object is already moving).
What is the coefficient of kinetic energy?
The coefficient of kinetic energy is a constant for friction acting as a retarding or dissipative force to calculate the total force on the object. The coefficient of friction u is represented in equation by the relation F = u*N, where N is the normal force.
