Solution: Consider the system shown in Fig. P6.81. The rope
Chapter 6, Problem 87P(choose chapter or problem)
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.
