Question

An object with a mass of `12 kg` is on a plane with an incline of `- pi/6`. If it takes `9 N` to start pushing the object down the plane and `5 N` to keep pushing it, what are the coefficients of static and kinetic friction?

Answer 1

Static friction coefficient is `0.08` and the dynamic is `0.04`.

Explanation:

Static friction coefficient:

Dynamic friction coefficient:
