A beer barrel has a mass of 10 kg and a volume of 20 liters. Assuming the density of beer is 1000 kg/m3, determine the total mass and weight of the barrel when it is filled with beer.
Balloons are often filled with helium gas because it weighs only about one-seventh of what air weighs under identical conditions. The buoyancy force, which can be expressed as Fb = ? airgVballoon, will push the balloon upward. If the balloon has a diameter of 12 m and carries two people, 70 kg each, determine the acceleration of the balloon when it is first released. Assume the density of air is ? =1.16kg/m3, and neglect the weight of the ropes and the cage
