When you push a 1.80 kg book resting on a tabletop it takes 1.90 N to start the book sliding. Once it is sliding, however, it takes only 1.50 N to keep the book moving with constant speed. What are the coefficients of static and kinetic friction between the book and the tabletop? static kinetic

Answer #1

Solution)

a) Here, coefficient of static friction

=1.9/(1.8*9.81) =0.107

======

B)

coefficient of kinetic friction

=1.5/9.81*1.8=0.085

=======

Good luck!:)

    2. A 3.80-kg hanging block is pulling against a 2.50-kg block on a tabletop, as shown, via a string over a pulley that is massless and frictionless. At the same time, a constant external force F = 5.50 N is pulling the tabletop block to the right, as shown. There is a static friction coefficient is = 0.75, and kinetic friction coefficient dx = 0.15, with the tabletop. (a) The blocks are initially stationary. With a calculation, determine whether the...
