question

An observation balloon has a volume of 300 m^3 and is filled with hydrogen of density 0.1 g/liter. The basket and passengers have a total mass of 350 kg. Find the initial acceleration when the balloon is released, assum-ing that the air resistance is zero when the velocity is zero. The density of air is 1.3 g/liter and the upward force on the balloon is equal to the weight of air dis-placed by the balloon.
