For instance: A pail of water of mass 20 kg is being lifted by a rope from a well. It is ascending with an acceleration of 2 m/s^2. Determine tension in the rope.© BrainMass Inc. brainmass.com June 4, 2020, 3:48 am ad1c9bdddf
See the attached file for a free-body diagram.
The mass of the pail and water in it = M = 20 ...
This solution shows how to calculate tension in a rope, using Newton's Second Law of Motion and F = ma, given mass and acceleration.
