The formula for the force of friction is Ff=μFn Where Ff is force friction; μ is the coefficient of friction; and Fn is Force Normal (The force that a surface pushes back on a object)
Force normal is equal to gravity times mass since the object is not falling or accelerating upwards.
Therefore your formula can be manipulated to:
Ff=μmg Where m is mass; and g is gravity (9.81)
Substitute your variables, therefore you get:
500N=μ(200kg)(9.81)
μ=0.254841998

What is the function of coefficient of static friction?
This coefficient of static friction is needed to find the frictional force between a body and a surface on which body has to move. If u (mu) is the coefficient of friction then uR gives the frictional force between moving body and surface. There is no unit for coefficient of friction. Here R is reaction which equals to the weight of the body
What does the coefficient of static friction represent?
In free space or on a frictionless surface, it takes no force to move something. Where there is friction, the ratio of (force necessary to start it moving horizontally)/(the object's weight) is the coefficient of static friction on the horizontal surface.
What is more sliding friction or static friction?
static friction is higher in most cases, if you're talking about the coefficient of static or kinetic friction
The force you have to overcome to start an object moving is .?
I have to guess either gravity or friction.If by that you mean a force that opposes the start of motion, then your force would be static friction.Static friction only occurs before an object starts moving, as opposed to kinetic friction which occurs when the objects is moving or sliding. The equation for static friction is: Ff = (coefficient of static friction) * FNInertia
What the value of abs plastic static friction coefficient?
With what material? Coefficient of friction is for two materials.
What does the slope of the static friction vs normal force represent?
the slope of static friction & normal force represents "coefficient of friction' which is constant for a particular surface
What happen to the static friction force as the mass is increased?
It increases. Static friction is the friction that opposes an object at rest to begin moving, given the following formula :- Fs = MsN, where ms is the coefficient of static friction, and n is the normal force, which is equal to mg if is at the x-axis. As the formula shows, the static friction increases with an increase in mass.
How does the coefficient of static friction for two surfaces in contact compare to the coefficient of kinetic friction for the same two surfaces?
The coefficient of static friction is always larger because it takes more initial force to move an object that is at rest.
Which coefficient of friction is greater static or kinetic?
static usully greater then kinetic
What is the formula for Coefficient of friction?
(Static coefficient of friction) Cf = horizontal force (newtons) required to overcome static resistance / vertical force (newtons) due to objects mass * acceleration due to gravity. Note: Moving friction coefficient is generally less.
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
Is there a formula for friction?
simple one is: max friction = coefficient of static friction*normal force
