An object of mass 100 kg is released from rest from a boat into the water and allowed to sink. While gravity is pulling the object down, a buoyancy force of 1/40 times the weight of the object is pushing the object up (weight = mg). Assume that water resistance exerts a force on the object that is proportional to the velocity of the object, with proportionality constant 10 N-sec/m. Answer the following questions. (a) Find the force due to gravity. Use g = 9.81 m/sec^2. (b) Find the buoyancy force. (c) Express the air resistance force using the given information. (d) Use Newton's second law to build a differential equation for the velocity v(t). What is the initial data? (e) Solve your initial value problem for v(t). You can use separation of variables or go by an integrating factor. (f) Use your result in step 'e' to find the position function x(t). ONLY PART E AND F, please and thank you!

However, the movement of blood is difficult to monitor directly. Instead, some medical devices use the Hall effect, taking advantage of the fact that the blood flowing through a vein contains a considerable number of free ions. Model the vein in a patient's arm to be of rectangular cross section, as shown in the figure, with a width w=4.00 mm and height ℎ=3.35 mm. The entire section of the vein is immersed in a constant magnetic field of ?=0.0955 T, pointing horizontally and parallel to the width. A medical device constantly monitors the resulting Hall voltage. Suppose that medical precautions mandate that the speed of the blood flow for this particular component of the body should never drop below 21.40 cm/s.
