What is the coefficient of kinetic friction between the book and the tabletop?μs = Fs/mg = .122μk = Fk/mg = .085Acceleration is 0 in both the X and Y directions for both cases (Constant velocity means acceleration is 0). To find the coefficient of friction you will first need to find the normal force. To do this use Newton’s Second Law: F = maF = ma (in Y direction)(Normal Force) – (1.85)(9.81) = (1.85)(0)Normal Force = 18.15 NF = ma (in X direction)(2.22) – (Coefficient of Static Friction)(18.15) = (1.85)(0)Coefficient of Static Friction = 0.122F = ma (in X direction again)(1.54) – (Coefficient of Kinetic Friction)(18.15) = (1.85)(0)Coefficient of Kinetic Friction = 0.085
