Determine the drag coefficient c needed for a parachutist of mass m = 68.1 kg to have a velocity of v = 40 m/s after free-falling for time t = 10 s. let the acceleration of gravity be g = 9.8 m/s2. recall the equation for free-fall velocity of an object:
(a) using calculus knowledge, follow example 1.1 to obtain the analytical solution for the velocity the case where the jumper is initially at rest (v = 0 at t = 0).
(b) repeat the numerical calculation for the velocity with the same initial condition and parameter values. use a value of 0.225 kg/m for.
(c) program in excel to obtain the analytical solution and numerical solution from t=0 to 20 seconds. plot both solutions in the same figure. provide me your programming code and figure.

An  atom  (ours, not carroll's) consists of a positively charged  nucleus, surrounded by one or more negatively charged particles called  electrons. the positive charges equal the negative charges, so the atom has no overall charge; it is electrically neutral. most of an atom's mass is in its nucleus; the mass of an electron is only 1/1836 the mass of the lightest nucleus, that of hydrogen. although the nucleus is heavy, it is quite small compared with the overall size of an atom. the radius of a typical atom is around 0.1 to 0.25 nanometres (nm), whereas the radius of a nucleus is about 10-6  nm.  *  if an atom were enlarged to the size of the earth, its nucleus would be only 200 feet in diameter and could easily rest inside a small football stadium.read more on -
