Homework Help: Balloon acceleration

  1. Mar 1, 2016 #1
    1. The problem statement, all variables and given/known data
    The mass of an empty balloon is 0.41 kg it got inflated with 0.0938 kg of helium which ressulted in his volume being 0.524 m^3 after being inflated then left to ascend considering the air's density is constant and is 1.30 kg/m^3 what is the acceleration of the balloon (dont consider air resistance)

    2. Relevant equations

    3. The attempt at a solution
    1.74/(0.41+0.0938)=3.45 m/s^2
    Tye answer sheet says its 16.4???
