A flight attendant pulls her 70.0 N flight bag a distance of 263 m along a level airport floor at a constant speed. The force she exerts is 41.0 N at an angle of 52.0° above the horizontal.
(b) Find the work done by the force of friction on the flight bag.
(c) Find the coefficient of kinetic friction between the flight bag and the floor.

at constant speed,
horizontal force*distance=workdone
where horizontal force is 41cos52
workdone= mg*mu solve for mu
