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.

Unpolarized light of intensity i_0=750w/m^2 is incident upon two polarizers. after passing through both polarizers the intensity is i_2=280w/m^2. (a) what is the intensity of the light after it passes through the first polarizer in w/m^2? (b) write an equation for the angle between the polarizers in terms of the initial (i_0) and final (i_2) intensities. (c) find the angle between the polarizers in degrees.
