Find the settling velocity of an 8 μm diameter particle with density 1500 kg/m3. If this particle had been hurled to a height of 7000 m during a volcanic eruption, estimate the time required to reach the ground (at sea level). You may assume that the viscosity of air does not change enough with altitude to be important. If winds average 8.0 m/s, how far away (horizontally) would it travel on its way down?
The mass density of air on Mars is ρ=0.016 kg/m3. The gravity on Mars is gMars= 3.7 m/s2. The mass density of air on earth under standard pressure and temperature conditions is ρ=1.225 kg/m3. A NASA mars probe weighs 1000 N on Earth. At terminal velocity, the weight of a falling object is equal to the drag force. Assume that the drag coefficient of the parachute used is constant, and has the same value on both Earth or Mars, and...

Calculate the terminal velocity for a pollen grain falling through the air using the drag force equation. Assume the pollen grain has a diameter of 7 µm and a density of 0.3 g/cm3. If this grain is released from the top of a tree (height 11 m), estimate the time it will take to fall to the ground. Hint: The pollen grain will reach its terminal velocity very quickly and will have this velocity for essentially the entire motion. Your...
