A flight attendant pulls her 66 N flight bag a distance of 318 m along a level airport floor at a constant velocity. The force she exerts is 43 N at an angle of 52° 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 friciton between the flight bag and the floor.
