The terminal velocity of a raindrop that is 4.00 mm in diameter is approximately 8.50 m/s under controlled, windless conditions. The density of water is 1.00×103 kg/m3. Recall that the density of an object is its mass divided by its volume. If we model the air drag as being proportional to the square of the speed, Fdrag=cv2, what is the value of c? Note 1 millimeter (mm) = 0.001 m

A car engine with a given weight of w, is suspended in air by a cable that is connected to a MASSLESS ring.

A object is shot vertically upward with an initial speed of 5 km/s . If there is no atmosphere, the max elevation of the object above earth’s surface would be equal to what? A- 1100km B-1300km C-1600km D- 8000km E- 25000km

What is most nearly the terminal velocity of a 50mm diameter solid aluminum sphere falling in air? the sphere has a coefficient of drag of 0.5, density of aluminum is 2650 kg/m^3 , and density of air is 1.225 kg/m^3.Answer: 53 m/s

Drag Force: A spherical particle of radius 5.9 cm and a mass of 226 g is moving through a fluid of the same density. (This means you can ignore the effects of gravity.) The position of the particle is given by x (t) 1 In (1+ bvot), where x is its position and t is the elapsed time. The initial speed vo is 27.8 m/s, and the constant b is 0.3 m-1. (b) What is the velocity of the particle after 3.3 seconds? (c) What is the acceleration of the particle after 3.3 seconds?

A probe on a dwarf planet collects 5 moles​ [mol] of dust material. The​ sample, which completely fills a cube with a side length of 4 centimeter​ [cm], weighs 0.19 newtons​ [N] on the dwarf planet. The density of the material is determined to be 3160 grams per liter​ [g/L].Determine the gravity of the dwarf planet in units of meters per seconds squared ​[m/s2​].
