Chapter 1, Problem 3P

Rather than the linear relationship of Eq. (1.7), you might choose to model the upward force on the parachutist as a second-order relationship,

F U = c ' v 2

where c ' = a bulk second-order drag coefficient (kg/m).

(a) Using calculus, obtain the closed-form solution for the casewhere the jumper is initially at rest ( v = a  at  t = 0 ) .

(b) Repeat the numerical calculation in Example 1.2 with the same initial condition and parameter values, but with second-order drag. Use a value of 0.22 kg/m for c .
