DEA agents watch drug smugglers load cocaine onto a fishing boat in a Mexican river to transport it down the river to the ocean, and then to Miami. To estimate how much cocaine was loaded, they measure how much further the boat sinks into the water after being loaded. If the boat’s area at the waterline is 50 m2 and it sinks by 2 cm, how much cocaine was loaded?
How many cubic meters of helium are required to lift a light balloon with a 370-kg payload to a height of 7,998 m? Take pu. = 0.179 kg/m3. Assume the balloon maintains a constant volume and the density of air decreases with the altitude z according to the expression
Pair = Poe-z/8,000, where z is in meters and Po = 1.20 kg/m is the density of air at sea level.
