A parcel is connected to a flying drone as illustrated above. Note that the coordinate system is given with +y pointed in the upwards direction. Holding the parcel, the drone takes off moving straight up with a velocity of 8.40. m/s. Note that, as usual, y = 0 at the ground. After 8.00 s, the drone accidentally releases the parcel! The parcel is in "freefall" immediately after it is released, as defined in Lecture 7. Assume that the magnitude of the acceleration, g = 9.81 m/s², and that the drone continues with the same velocity after releasing the parcel. Ignore the effects of air-resistance.

How many cubic meters of helium are required to lift a balloon with a 400-kg payload to a height of 8 000 m? Take He = 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 air = 0ez/8, where z is in meters and 0 = 1.20 kg/m3 is the density of air at sea level.

An airplane has a mass of 2.1×106 kgkg , and the air flows past the lower surface of the wings at 81 m/sm/s . If the wings have a surface area of 1100 m2m2 , how fast must the air flow over the upper surface of the wing if the plane is to stay in the air? Express your answer to two significant figures and include the appropriate units.

The most dangerous particles in polluted air are those with diameters less than 2.5 μm because they can penetrate deeply into the lungs. A 15-cm-tall closed container holds a sample of polluted air containing many spherical particles with a diameter of 2.5 μm and a mass of 2.6 x 10-14 kg. How long does it take for all of the particles to settle to the bottom of the container?
