A 27.0 kg block resting on a horizontal table is connected to an empty 3.50 kg bucket that is hanging over the edge of the table by cord running over a frictionless pulley. The coefcient of kinetic friction between the block and the table is 0.228. Assume g = 9.8 m/s"2. b) When 20.0 kg of sand is added to the empty bucket, the block slides. What is the magnitude of the tension in the cord in Newtons when the block is sliding? (Enter an integer answer with no units in the space below.)
