Consider the system shown in the figure. Block A has weight 4.91 N and block B has weight 2.94 N. Once block B is set into downward motion, it descends at a constant speed. Assume that the mass and friction of the pulley are negligible. Calculate the coefficient of kinetic friction mu between block A and the table top. I'm not sure where to begin.
Consider the system shown in the figure below. Block A weighs 43.2 N and block B weighs 29.0 N. Once block B is set into downward motion, it descends at a constant speed.
