A consumer upset with the latest trend of postal rate increases has decided to try to send letters by balloon even though they may not reach their intended destinations. A 79200 cm³ gas-filled balloon will provide enough lift for a 43.4 g package to be accelerated upward at a rate of 3.25 m/s². For these circumstances, calculate the density of the gas the consumer fills the balloon with. The acceleration due to gravity is g = 9.81 m/s² and the density of air is Pair = 1.16 kg/m³. Neglect the mass of the balloon material and the volume of the package. p = kg/m³

Question
A consumer upset with the latest trend of postal rate increases has decided to try to send letters by balloon even though they may
not reach their intended destinations. A 79200 cm³ gas-filled balloon will provide enough lift for a 43.4 g package to be
accelerated upward at a rate of 3.25 m/s2. For these circumstances, calculate the density of the gas the consumer fills the balloon
with. The acceleration due to gravity is g = 9.81 m/s? and the density of air is pair = 1.16 kg/m³. Neglect the mass of the
balloon material and the volume of the package.
p =
kg/m
