A 27.0 kilogram block is connected to an empty 1.00 kilogram bucket by a cord running over a frictionless pulley. The coefficient of static friction between the block and the table is 0.435 and the coefficient of kinetic friction between the block and the table is 0.320. S and is gradually added to the bucket until the system just begins to move.
(a) Find the mass of sand added to the bucket.
(b) Find the acceleration of the system.
