2009 F = ma Exam — Question 15

15. A 22.0 kg suitcase is dragged in a straight line at a constant speed of 1.10 m/s across a level airport ﬂoor by a student on the way to the 40th IPhO in Merida, Mexico. The individual pulls with a 1.00 x 102 N force along a handle with makes an upward angle of 30.0 degrees with respect to the horizontal. What is the coeﬃcient of kinetic friction between the suitcase and the ﬂoor? — Source: Question 15, 2009 F = ma Exam, © 2009 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
