Several people are riding in a hot-air balloon the combined, Ask an Expert

Academics

Several people are riding in a hot-air balloon. The combined mass of the people and balloon is 348 kg. The balloon is motionless in the air, because the downward-acting weight of the people and balloon is balanced by an upward-acting "buoyant" force. If the buoyant force remains constant, how much mass should be dropped overboard so the balloon acquires an upward acceleration of 0.236 m/s2?
