A 28.0-kg block is connected to an empty 2.56-kgbucket by a cordrunning over a frictionless pulley. The coefficient of staticfriction between the table and the block is 0.41 and thecoefficient of kinetic friction between the table and the block is0.32. Sand is gradually added to the bucket until the system justbegins to move. Ignore mass of cord. (Figure 1)
Calculate the mass of sand added to the bucket.
Calculate the acceleration of the system.
