A 28.0-kg block is connected to an empty 1.00-kg bucket by a cord running

over a frictionless pulley. The coefficient of static friction between the table and

the block is 0.450 and the coefficient of kinetic friction between the table and the

block is 0.320. Sand is gradually added to the bucket until just before the system

begins to move.

a. Determine the tension in the cord. Use the summation of the forces in the x- and y-directions for the block to find your answer.
