A hot-air balloon is accelerating upward under the influenceoftwoforces, its weight and the buoyant force. Forsimplicity,considerthe weight to be only that of the hot air withintheballoon, thusignoring the balloon fabric and the basket. Thehotair inside theballoon has a density of ?hot air = 0.93 kg/m3,andthe density ofthe cool air outside is ?cool air = 1.29 kg/m3.Whatis theacceleration of the rising balloon?
