2) Consider the system shown in the figure. Masses of the pulley and rope are neglected and the pulley is frictionless. Initially, the 6 kg-block moves downwards and the 8 kg-block moves to the right at a speed of 0.9 m/s (notice that both blocks have the same speed). Both blocks stops after moving 2 m. Using the work-energy theorem, calculate the coefficient of kinetic friction between the 8 kg-mass and and the table surface.
