co-efficient of kinetic friction
If you use a horizontal force of 30N(newton) to slide a 12kg wooden crate across the floor at a constant velocity what is the coefficient of kinetic friction between the crate and the floor?
I heard this but i'm not too sure if the formula was
Kinetic force = F/N or something, anyways here's the problem
I would appreciate if the work is shown, i need to know how to solve this
When you slide the wooden crate along the floor the kinematic friction will act against the direction of travelling.Since the crate is travelling at a constant speed without acceleration the forces acting on it are at a equilibrium state. This is also related to Newton's first law.
Sliding force `=` Friction force (F)
`30N = F`
Friction force (F) is given as a product of normal force(N) and coefficient of kinetic friction(`mu` ).
`F = mu*N`
`mu = F/R`
So the coefficient of kinetic friction is 0.255.
