A 28.0-kg block is connected to an empty 2.50-kgbucketby a cord running over a frictionless pulley. The coefficient of static friction between the table and the block is 0.41 and the coefficient of kinetic friction between the table and the block is 0.32. Sand is gradually added to the bucket until the system just begins to move. Ignore massof cord. (Figure 1)   Calculate the mass of sand added to the bucket. Express your answer to two significant figures and include the appropriate units.   Calculate the acceleration of the system. Express your answer to two significant figures and include the appropriate units
