QUESTION:

Consider the system shown in Fig. P6.81. The rope and pulley have negligible mass, and the pulley is frictionless. Initially the \(6.00-\mathrm{kg}\) block is moving downward and the \(8.00-\mathrm{kg}\) block is moving to the right, both with a speed of \(0.900 \mathrm{~m} / \mathrm{s}\). The blocks come to rest after moving \(2.00 \mathrm{~m}\). Use the work-energy theorem to calculate the coefficient of kinetic friction between the \(8.00-\mathrm{kg}\) block and the tabletop.
