A flight attendant pulls her 63.7 N flight bag a distance of 336 m along a level airport floor at a constant velocity. The force she exerts is 44.4 N at an angle of 65.7° above the horizontal.
-Find the work she does on the flight bag.
-Find The work done by the force of friction on the flight bag.
-Find the coefficient of kinetic friciton between the flight bag and the floor.
