Problem Set C

Problem #8:

A 4.89-kg bucket suspended by a rope is moving upwards with a constant velocity of 5.7 m/s. Determine the tension (in Newtons) in the rope.

• 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
