Question
In the figure, two blocks are attached to each other by a massless string that is wrapped around a
frictionless pulley. When the bottom 4.00-kg block is pulled to the left by the constant force P, the
top 2.00-kg block slides across it to the right.
Find the magnitude of the contact force acting on the bottom of the 4.00kg block if force P is about
to move the block at a constant speed. Assume that the coefficient of kinetic friction between all
surfaces is 0.400.
