172 = A free-falling object close to the surface of the earth accelerates at a constant rate g. Assuming that the upward direction is positive, the equation -9 is the differential equation governing the vertical height coordinate y(t) of the falling body at time t. Here t = 0 is taken to be the initial time when the object starts to fall. If we assume further that the object is tossed upwards from a height yo with an initial velocity...

5. In certain circumstances, we can model the velocity of a falling mass subject to air resistance as - dv m7 = mg – kv?, where v (t) is the velocity of the object, m is the mass of the object, g is acceleration due to gravity, and k is a constant of proportionality. Assume the positive direction is downward. (a) Solve this equation subect to the initial condition v (0) = vo. (b) What is the terminal velocity of...

25.19 Assuming that drag is proportional to the square of velocity, we can model the velocity of a falling object like a parachutist with the following differential equation: dv dt where v is velocity (m/s), 1 = time (s), g is the acceleration due to gravity (9.81 m/s), c = a second-order drag coefficient (kg/m). and m 90-kg object with a drag coefficient of 0.225...

6. [10 points) For the following question, to model the free fall of a falling rock, assume the usual idealizing simplifications for solving "free fall" problems. Work with the approximate value g = 9.8 m/s2 for the Earth's gravitational acceleration. Consider the following experiment. The Leaning Tower of Pisa is known worldwide for its nearly four- degree lean. The height of the tower is 55.86 meters from the ground on the low side, and 56.67 meters on the high side....

6. Many IVPs are autonomous, meaning the independent variable doesn't appear explicitly on the right hand side. Such is the case for the differential equation describing the velocity of a falling object: In this autonomous equation, g is the acceleration due to gravity (32 ft/s2). The first term on the right hand side models the air resistance or drag on the object, and k is a constant that depends on the shape and size of the falling object. The choice...

Why do we need to assume constant viscosity for a flowing fluid system when using the equations for momentum balances, since viscosity term is already outside the partial differential sign/ function.
