. What was the net force acting on your balloon as it was released?
i know the mass is 65 N but dont know the acceleration and need to mind the mass
i cant use F=MA because i dont know the acceleration

And, since we don't know *any* thing about the baloon (volume, content, pressure, etc.) we can't even use bouyancy calculations to get an approximation of the force.
BTW.... N (Newtons) are a unit of force, *not* mass, so 65N of mass is kinda meaningless.

the galaxies rotate at speeds inconsistent with their obvious mass is given that we do see it all. I am relating to it as being the theoretical Dark Matter. There are very powerful proofs that shows that darkish topic exist. One the is the inconsistent pace of and obvious mass. darkish topic makes up approximately seventy five% to eighty% of the problem within the Universe...
