Find the terminal velocity (in m/s) of a spherical bacterium (diameter 1.73 µm) falling in water. You will first need to note that the drag force is equal to the weight at terminal velocity. Take the density of the bacterium to be 1.10 ✕ 103 kg/m3. (Assume the viscosity of water is 1.002 ✕ 10−3 kg/(m · s).)

A little girl with a mass of 49 kilograms is falling to Earth using a parachute. How much air drag does she need so that she falls at terminal velocity? Newtons
If the radius of a space station is 50m, what angular velocity is necessary so that a person of mass 80kg is subjected to a centrifugal force against the floor of the space station which equals their weight force on earth?
For a human body falling though air in a spread-eagle position, the numerical value of the constant D is about D = 0.250 kg/m Part A What value of D is required to make ut = 43.0 m/s the terminal velocity of a skydiver of mass 76.0 kg Express your answer using two significant figures. EVO AEO ? kg/m Submit Request Answer Part B If the sky diver's daughter, whose mass is 46.0 kg, is falling through the air and...
. Terminal velocity - free fall. Estimate (order of magnitude) the terminal speed vT of a typical human in free fall. Draw a free body diagram for the person falling at terminal velocity. Use the FBD, Newton’s second law, and the formula for air resistance (drag force) mentioned in class FD = 1/2 D ρ A v2 to find an expression for vT . Explain/justify any assumptions that you make (e.g., for quantities like the cross-sectional area A or the...
When an object is falling in air at terminal velocity, (choose all correct answers) Group of answer choices the net force on the object is down. the net force on the object is zero. the net force on the object is up. there is no gravitational force on the object. there is a gravitational force on the object up. there is a gravitational force on the object down. the velocity is decreasing. the velocity is increasing. the velocity is constant.
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...
If a dense 20.0-kg object is falling in air at half its terminal velocity (drag force is proportional to the square of the object’s speed), what is the drag force on the object at this moment? a. 25 N b. 50 N c. 75 N d. 100 N e. 150 N
a) A 100-g apple is falling from a tree. What is the impulse that Earth exerts on it during the first 0.50 s of its fall? The next 0.50 s? b) The same 100-g apple is falling from the tree. What is the impulse that Earth exerts on it during the first 0.50 m of its fall? The next 0.50 m? A 100- apple is falling from a tree. What is the impulse that Earth exerts on it during the...
