A 4.80-kg bucket of water is accelerated upward by a cord of negligible mass whose breaking strength

Question:

A 4.80-kg bucket of water is accelerated upward by a cord of negligible mass whose breaking strength is 75.0 N.
(a) Draw the free-body force diagram for the bucket. In terms of the forces on your diagram, what is the net force on the bucket?
(b) Apply Newton's second law to the bucket and find the maximum upward acceleration that can be given to the bucket without breaking the cord.
