Question 33307

Numerical Methods

In this example of the free-falling parachutist, we assumed that the acceleration due to gravity was a constant value. Although this is a decent approximation when we are examining falling objects near the surface of the earth, the gravitational force decreases as we move above sea level. A more general representation based on Newton's inverse square law of gravitational attraction can be written as presented in Eq.1
g(x)=g(0) \frac{R^{2}}{(R+x)^{2}}
\frac{d v}{d t}=g-\frac{c}{m} v
where g(x) = gravitational acceleration altitude x (in m) measured upward from the earth's surface (m/s²), g(0)=gravitational acceleration at the earth's surface (9.81 m/s³),and R = the earth’s radius (6.37 x 106 m).
(a)In a fashion similar to the derivation of (Eq. 2) use a force balance to derive a differential equation for velocity as a function of time that utilizes this more complete representation of gravitation. However, for this derivation, assume that upward velocity is positive. (20 points)
(b)For the case where drag is negligible, use the chain rule to express the differential equation as a function of altitude rather than time. Recall that the chain rule is:
\frac{d v}{d t}=\frac{d v}{d x} \frac{d x}{d t} \text { (25 points) }
(c)Use calculus to obtain the closed form solution where v = vo at x = 0.
(d)Use Euler's method to obtain a numerical solution from x = 0 to 100.000 m.using a step of 10,000 m where the initial velocity is 1500 m/s upward. (25
(e)Compare your result with the analytical solution.

Derive the mathematical model and perform the calculation from t = 0 to 20 s with a step size of 1 s. Use an initial condition that the parachutist has an upward velocity of 20 m/s at t = 0. At t = 10 s, assume that the chute is instantaneously deployed so that the drag coefficient jumps to 50 kg/s. (Show all steps)
