Can anyone help me with this problem?
A flight attendant pulls her 70.0 N flight bag a distance of 258 m along a level airport floor at a constant speed. The force she exerts is 32.0 N at an angle of 52.0° above the horizontal. Find the work she does on the flight bag and the work done by the force of friction of the flight bag.
I was able to make a free body diagram and see that the weight of the flight bag is 70 Newtons, the displacement is 258 m. But when I solved for W, which is force x displacement x cosine 52 degrees I got the wrong answer.
(70 x 258 x cos52).
