Calculating Velocity of a Falling Object with Drag Force
Ok, so here's my best attempt at this: m(dv/dt)=mg-KV dv/dt=g-KV/m 1/(g-KV/m)dv=dt (1) Now from here we can use u-substitution: u=g-KV/m du/dv=-K/m or dv=(-m/K)du Subbing this into equation 1: (-m/K)(1/u)du=dt or (1/u)du=(-K/m)dt Now integrate both sides: ln(u) = (-K/m)(t+C)...- sn0wxboarder

Calculating Velocity of a Falling Object with Drag Force
First, let me preface this question that I have been out of academia for about 5 years now, and am just starting to get back into it, although it seems my Calc/Kinematics is a little rusty.b]1.
