A flight attendent pulls her 78.6 N flight bag a distance of 344 m along a level airport floor at a constant velocity. The force she exerts is 44.8 N at an angle of 64.2 degrees above the horizontal.
Find the coefficient of kinetic friction between the flight bag and the floor?
Please furnish calculations.

  1. The exerted force along the floor direction is 44.8 cos 64.2 = 19.5 N
    That equals the bag's weight times the kinetic friction coefficient, Uk, since there is no acceleration.

    19.5 = 78.6 Uk
    Solve for Uk
