A 28.0 kg block is connected to an empty 2.00 kg bucket by a cord over a frictionless pulley. The coefficient of static friction is 0.45 and the coefficient of kinetic friction is 0.32. Sand is gradually added to the bucket until the system begins to move.
a) Calculate the mass of the sand added to the bucket.
b) calculate the acceleration of the system
