A block of mass .5kg is ona table and attached to a block of mass .25kg by a taut massless string. The .25kg block hangs by means of the string, which goes over a pulley. The .25kg block is released, and it descends from rest at a constant acceleration, travelling 1.00m in 1.25s. What is the coefficient of kinetic friction between the table and the .5kg block?
