Question

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?

Answer 1

Static friction coefficient=`0.15`
Kinetic friction coefficient=`0.175`

Explanation:

.
But your question seems to be wrong as `mu_s` cannot be less than`mu_k`.
