A 6-kg bucket of water is being pulled straight up by a string at a constant speed. At a certain point the speed of the bucket begins to change. The bucket now has an upward constant acceleration of magnitude 3 m/s2. What is the tension in the rope now

anonymous · Answer

So I know the basic F=ma so 6x9.8=58.8 N, but what about the other part. of 3m/s2?

anonymous · Answer

i think i understand. 9.8+3=12.8
12.8x6kg=76.8N can someone confirm

festinger · Answer

Sum of all forces = ma.

If you draw a free body diagram you should see that:
ma=T-mg.
6(3)=T-6(9.8)

anonymous · Answer

we have to get the total acceleration to solve the problem. 9.8+3
ok, so i drew the diagram on my paper,  worked it differently then what you suggested and go the exact same answer
