University physics 6.81: calculate the friction. consider the system shown below. the rope and pulley have negligible mass, and the pulley is frictionless. initially the 6.00 kg block is moving downward and the 8.00 kg block is moving to the right, both with a speed of 0.900 m/s. the blocks come to rest after moving 2.00 m. calculate the coefficient of kinetic friction between the 8.00 kg block and the tabletop.
