Consta
A 28.0-kg block is connected to an empty 2.12-kg
bucket by a cord running over a frictionless pulley. The
coefficient of static friction between the table and the
block is 0.45 and the coefficient of kinetic friction between
the table and the block is 0.30. Sand is gradually added
to the bucket until the system just begins to move. Ignore
mass of cord. (Figure 1)
