(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The handle of a floor mop makes an angle θ = 39.6° with the horizontal. Assume the handle is massless, and the mop has mass M = 3.07 kg. The coefficient of kinetic friction between the mop and the floor is μk = 0.386. Find F, the magnitude of the force, exerted downward along the handle, that will cause the mop to slide across the floor without acceleration.

2. Relevant equations

Frictional force = μ*Normal force

Components

F=ma

3. The attempt at a solution

The bigger problem that I'm not understanding ishowto solve the problem. They are asking for a force to push down the handle so that acceleration will become 0, or so that the mop moves at a constant velocity. I don't know where to start...
