I came across one other problem that stumped me. 1) I have a mass of 65.0kg. How many helium balloons will be required to keep me afloat? The volume of the balloons is 0.25m^3. The density of the air is 1.7kg/m^3 and the density of helium is around 1.2kg/m^3. Ignore the mass of rubber used...

Then the water will fall out of the bucket I assume. Ohhhhh. So it has to be atleast 9.8 m/s?

Could I get some clarification of #5 and #3 as to what you mean. For 5 am I supposed to be using a form of a=V^2/r?
