Question
A 12.0kg bucket is lowered vertically by a rope in which there is 180 N of tension at a given instant.
What is the acceleration of the bucket?
Is it up or down?

If you draw a free-body diagram for the bucket, you will end up with the following (shown sideways)
TOP---->180N<------BUCKET-------->12g N BOTTOM
Since 180N > 12g=12*9.8=117.6
the acceleration is upwards.
Net upward force = 180-117.6,
mass = 12 kg
Acceleration = ??? using F=ma
