Homework Help: Physics

Posted by Name on Sunday, June 23, 2013 at 4:48am.

A hot-air balloon is accelerating upward under the influence of two forces, its weight and the buoyant force. For simplicity, consider the weight to be only that of the hot air within the balloon, thus ignoring the balloon fabric and the basket. The hot air inside the balloon has a density of ˝hot air = 0.93 kg/m3, and the density of the cool air outside is ˝cool air = 1.29 kg/m3. What is the acceleration of the rising balloon?
