You decide to go for a ride in a hot-air balloon. You are hovering at a low altitude. (That is, you are neither accelerating upward nor downward.) The total weight of the balloon (including ita load and the hot air in it) is 1.7 × 104 N. (Take atmospheric pressure = 1 atm = 105 Pa and g = 10 m/s2.) 1)What is the weight of the surrounding air that is displaced by the balloon? Weightair = 2)What is the volume of this displaced air? (Take the density of air to be 1.21 kg/m3.) Vair = 3)At the end of your ride, the balloon descends at 0.2 m/s2. Calculate the magnitude of the net force acting on the balloon.Fnet = 4)Calculate the magnitude of the buoyant force acting on the balloon. FB =
