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 Fb=density*volume*g Fg=mg Fnet a=Fnet/m 3. The attempt at a solution Fb=1.30*0.524*9.81=6.68257N Fg=(0.41+0.0938)9.81=4.94N 6.68-4.94=1.74N 1.74/(0.41+0.0938)=3.45 m/s^2 Tye answer sheet says its 16.4???
