The solution presentation shown emphasizes importance of gathering information in a coherent manner. The guiding idea is the NEED-TO-KNOW. For the case at hand we need to know the acceleration of the bucket. By simply asking "How would I find out?" Newton's law of motion provides an appropriate response. Now we NEED-TO-KNOW the net force. The idea of a free-body diagram provides a response. The process is continued, each step being a consequence of the previous step and a precursor to the next step. Problem solve themselves.
