Problem Set C

Problem #7:

A 4.89-kg bucket suspended by a rope is accelerated upwards. If the tension in the rope is 96.7 Newtons, then determine the acceleration (in m/s/s) of the bucket.

• Read the problem carefully and diagram the physical situation (free-body diagram)
• Identify known and unknown information in an organized manner (list on diagram)
• Take the time to plot out a strategy prior to beginning the solution
• Identify an appropriate formula to use
• Perform step-by-step algebraic manipulations
