A flight attendant pulls her 69.1 N flight bag

a distance of 280 m along a level airport floor
at a constant velocity. The force she exerts is
32.7 N at an angle of 50.2◦ above the horizon-
tal.

a) Find the work she does on the flight bag.
Answer in units of J.

b) Find the work done by the force of friction
on the flight bag. Answer in units of J.

c) Find the coe�cient of kinetic friction be-
tween the flight bag and the floor.
