Ok, here is my dilemma: A flight attendant pulls her 70.0 N flight bag a distance of 253 m along a level airport floor at a constant velocity. The force she exerts is 40.0 N at an angle of 52 degrees above the horizontal. Find the following:(adsbygoogle = window.adsbygoogle || []).push({});

a) the work she does on the flight bag

b) the work done on the flight bag

c) the coefficient of kinetic friction between the flight bag and the floor

What I did for a was, I multiplied the force of the bag (70)*the distance (253)*cos(theta). For the answere I got 10903.4 J.

Then for b, I did the same thing, except used 40, and I got 6230.5

Am I doing this right so far?

For c, I have no clue how to solve for the coefficient of kinetic friction. Whenever I try an equation, it comes out greater than one, or, I have another variable to solve for.

Is there something that I am forgettting in the equation?
