An unknown object is placed inside of a spherical container and dropped from an airplane. When empty, the spherical container has a mass of 3.00 kg. The container has a drag coefficient of 0.500 and a diameter of 39.2 cm. With the unknown object inside, the container reaches a terminal velocity of 65.2 m/s. What is the mass of the unknown object? Use 1.22 kg/m​^3 ​​for the density of air.

Imagine that you are working for a salvage company. An empty shipping container was accidently dropped by a crane while being loaded onto a cargo ship. It is now sitting at the bottom of the harbour, 12 metres below the surface of the water. It needs to be moved as it is blocking ships from using the wharf. The shipping container is 6.06 m long, 2.59m high and 2.43 m wide, has a usable internal volume of 33 cubic metres,...

A skydiver of mass m = 70 kg, which includes the mass of all the equipment she is wearing (helmet, parachute, etc.), jumps from an airplane at high altitude. The density of the air is ρ = 1.22 kg/m3 . (a) Estimate a numerical value for the terminal speed of the diver while she is in a horizontal spread-eagle formation. (Parachute is not open.) The drag coefficient of the diver in this formation is about 1.0. Any other needed quantities...

The mass of a bicyclist and bike is 80 kg. The drag coefficient is 0.79. Frontal area is 0.42 m^2. The density of air is 1.1 kg/m^3 at this elevation. The terminal velocity is reached when the drag force of a free falling object is equal to the weight. a)Estimate the magnitude of the terminal velocity of the cyclist after he has ridden his bike off of a cliff. Assume that the frontal area remains constant during the fall. b)Estimate...

A spherical object (50 cm diameter, c=0.46 kJ/kg*C, k = 42 W/m*C, density = 7800 kg/m3 ) is initially at a uniform temperature of 450 C. It is suddenly placed in a constant temperature environment of 100 C. The convection transfer coefficient is 500 W/m2*C. How long would it take for temperature in the center of the sphere to cool down to 150 C? Note: Bi for a sphere is (hD)/(6k).Suggestion: First calculate Biot number, then determine if T is...
