A spherical raindrop of mass 0.00985 g and radius 1.33 mm falls from a cloud that is at a height of 1299 m above the ground. Assume the drag coefficient for the raindrop is 0.60 and the density of the air is 1.3 kg/m3. What is the raindrop's terminal speed? Please describe a steps
A 6.5-cm-diameter ball has a terminal speed of 26 m/s. What is the ball’s mass? Use ρ = 1.2 kg/m3 for the density of air at room temperature.
A soccer ball has a diameter of about 23 cm and a mass of about 425 g. What is its terminal velocity? (The density of air is 1.3 kg/m3.) ___ m/s
A spherical raindrop (r = 0.0015 m) falls from a cloud. The drag coefficient is 0.60. The density of the water is 1000 kg/m^3 and the density of the air it falls through is 1.2 kg/m^3. The shape of the drop doesn’t change during the fall, and the terminal velocity is 7.3 m/s. At this terminal speed, what is the magnitude of the resistive force acting on the drop?
18. Jonah throws a rock off the Empire State Building, and it quickly reaches terminal velocity. Find the terminal velocity of the rock as it falls vertically, given the following information: drag coefficient = 0.75; air density = 1.2 kg/m3; cross-sectional area of the rock = 5e-5 m²; mass of the rock = 27 g.

A 545-g squirrel with a surface area of 880 cm2 falls from a 4.0-m tree to the ground. Estimate its terminal velocity. (Use the drag coefficient for a horizontal skydiver. Assume that the cross-sectional area of the squirrel can be approximated as a rectangle of width 11.2 cm and length 22.4 cm. Note, the squirrel may not reach terminal velocity by the time it hits the ground. Give the squirrel's terminal velocity, not it's velocity as it hits the ground.)...

1.) Find the terminal velocity (in m/s) of a spherical bacterium (diameter 1.94 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).
