# Problem based on Newton's Second Law of motion

If a body is subjected to several forces, we must first find the net force on the body and then apply F=ma to determine its acceleration.

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.
