Calculate the terminal speed for a bacterium in water. Use the expression for the drag force in
Question:
Calculate the terminal speed for a bacterium in water. Use the expression for the drag force in Equation 3.23. Assume the bacterium has a mass m = 4 × 10–15 kg, a drag coefficient C = 0.02 N • s/m2 and can be approximated as a sphere of radius r - 1 μm. How long does it take a bacterium to fall from the top of a lake of depth 5.0 m to the bottom?

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
