If we have an upward moving sphere with 0.4 m3 volume and 100 kg mass , according to Archimedes buoyancy force = 4000 N so acceleration = 40 m/s^2
But according to Atwood's principle , buoyancy force ≈ 1600 N acceleration = 16 m/s^2
what makes such big difference . ( ignore drag force and downward weight force , i am talking about upwards force only liquid:water ) http://en.wikipedia.org/wiki/Buoyancy#Beyond_Archimedes.27_principle
