A question that I've spent hours on, but still can't seem to extract friction from it: 10.) A flight attendant pulls her 70.0N flight bag a distance of 253m along a level airport floor a a constant velocity. The force she exerts is 40.0N an angle of 52.0 Degrees horizontal. Find the following b. the work done by force of friction on the flight bagc. the coefficient of kenetic friction between the flight bag and the floor Any suggestions?
