1. ### Finding the angle when given the coefficient of friction

THANKS!! I finally did it! Thank you so much! :D
2. ### Finding the angle when given the coefficient of friction

Well I tried that, but then I got stuck... The F's cancel out. Move the sinθ to the other side, so you get Cosθ/Sinθ = 0.3 then I got stuck, I was thinking perhaps you could use trigonometric proofs?
3. ### Finding the angle when given the coefficient of friction

Thanks, so if Fcosθ = Friction And if friction = the coefficient of friction x the reaction force, and the reaction force (R) = Fsinθ would it be... Fcosθ = 0.3 x Fsinθ?
4. ### Finding the angle when given the coefficient of friction

The normal force would be equal to friction, as the mop is moving at constant velocity, Fr=coefficient of friction x the normal force?
5. ### Finding the angle when given the coefficient of friction

Thanks, I remember now, so the horizontal component is Fcosθ the vertical component would be Fsinθ i still don't see how that will help, as you don't actually have F or θ
6. ### Finding the angle when given the coefficient of friction

Well the horizontal force would be cos θ = 0.3/F I'm not too sure on the vertical component as you don't actually have the opposite side?
7. ### Finding the angle when given the coefficient of friction

Homework Statement A mop is being used to clean a floor. The coefficient of friction between the mop and floor is 0.3. Find the angle between the handle and the horizontal when the mop head is moving at constant velocity. Homework Equations The coefficient of friction = Friction/ Normal...
