A flight attendant pulls her 70.0 N flight bag a distance of 247 m along a level airport floor at a constant speed. The force she exerts is 33.0 N at an angle of 52.0° above the horizontal.
(a) Find the work she does on the flight bag.
(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.
