A flight attendant pulls her74 N flight bag a distance of210 m along a level airport floor at aconstant velocity. The force she exerts is 38 N at an angle of 57°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 flightbag.
(c) Find the coefficient of kinetic friciton between the flight bagand the floor.
