here's the question:
Part a of the drawing shows a bucket of water suspended from the pulley of a well; the tension in the rope is 81.5 N. Part b shows the same bucket of water being pulled up from the well at a constant velocity. What is the tension in the rope in part b?

equations: F=ma; maybe sin, cos, etc...?
i don't even know where to begin with this since the second situation has no angle given to help solve for the problem. i know that the bucket at rest and the bucket at constant velocity have a=0. i also figured that in situtation 1, since only tension and weight are acting on the bucket in the y direction, the weight equals -81.5. but i do not know where to go from there. any help is appreciated. thanks!
