A 6.45-m radius air balloon loaded with passengers and ballast is floating at a fixed altitude. Determine how much weight (ballast) must be dropped overboard to make the balloon rise 116 m in 23.0 s. Assume a constant value of 1.2 kg/m3 for the density of air. Ballast is the weight of negligible volume that can be dropped overboard to make the balloon rise. N
Use g = 9.8 m/s2.
