Archimedes says: volume of fluid displaced * density of fluid * g = upward buoyant force = weight is neutrally buoyant mass = weight/g = volume*density 2500 * 1.225 = 3063 kg up now subtract the mass of air in the balloon 2500 * rho what is rho, the
Net force on monkey: Fnet = weight - tension = mg - T Newton's 2nd Law: mg - T = ma Solve for "T": T = m(g-a) To avoid breaking, T can be no more than 2/3 of monkey's weight: T ≤ (2/3)mg Substitute "m(g-a)" for T: m(g-a) ≤ (2/3)mg Solve this inequality
