A large balloon of mass 222 kg is filled with helium gas


A large balloon of mass 222 kg is filled with helium gas until its volume is 335 m3. Assume the density of air is 1.29 kg/m3 and the density of helium is 0.179 kg/m3.

(a) Draw a force diagram for the balloon. (Do this on paper. Your instructor may ask you to turn in this work.)

(b) Calculate the buoyant force acting on the balloon.

N

(c) Find the net force on the balloon and determine whether the balloon will rise or fall after it is released.
