Hi, the question is like in the picture. How hard should she pull the string to raise with constant speed? She weighs 70 kg together with the bucket.

3. The attempt at a solution

The system must have 0 acceleration, but does this mean she should pull the string with an acceleration equal tog, to balance with it? Or is it enough that she pulls equal to her weight? But in this case, she would not raise.

This is a simple question, I guess, but I'm confused. Thanks for any help :)
