# An object with a mass of 8 kg is on a plane with an incline of  - pi/3 . If it takes 6 N to start pushing the object down the plane and 7 N to keep pushing it, what are the coefficients of static and kinetic friction?

Static friction coefficient=$0.15$
Kinetic friction coefficient=$0.175$
But your question seems to be wrong as ${\mu}_{s}$ cannot be less than${\mu}_{k}$.
