Fx=21N N=44.1N and F=μN
SO
μk=.48 or about .5

The normal force is the weight minus the vertical component of the pull. The horizontal component of the pull is equal to the force of kinetic friction because the mass is not accelerating, according to Newton's second law.

If you still don't get it after that explanation, you're a f*cking retard.

So who takes this class? Taken it? I have weekly problem sets I have to do, and got stuck here....

A flight attendant pulls her 69.1 N flight bag
a distance of 280 m along a level airport floor
at a constant velocity. The force she exerts is
32.7 N at an angle of 50.2◦ above the horizon-
tal.

Find the coefficient of kinetic friction be-
tween the flight bag and the floor.
