## Homework Statement

Barney is practicing his sweeping techniques for an upcoming curling tournament. He exerts a force on a 1.1-kg broom as he walks across a tile floor at a constant speed. The coefficient of friction between the floor and the broom is 0.45 and the broom handle makes an angle of 41° with the horizontal. Determine the amount of force with which Barney pushes downward (along the handle of the broom) in order to achieve this constant speed motion. Begin with a free body diagram. (ans: 10.6N)

## Homework Equations

F=ma

## The Attempt at a Solution

I created a FBD and using the info from the question I came up with

(10.78N)+(Fsin41°)=Fnorm

Fn=11.44N

(0.45)(Fn)=Fcos41°

F=6.82N now if this is my horizontal force then it will be the same as my friction force since the broom isn't accelerating.

If I want the force on the broom then using SOH CAH TOA. I take A/cos41 = 9.03N. I'm at a loss of how to find 10.6N
