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

Static friction coefficient= $0.15$ $0.15$
Kinetic friction coefficient= $0.175$ $0.175$

But your question seems to be wrong as $μ_{s}$ $mu_s$ cannot be less than $μ_{k}$ $mu_k$ .
