A person who weighs 200 lbs is falling through the sky while attached to a parachute. The equation of the downward velocity as a function of time for this is:(adsbygoogle = window.adsbygoogle || []).push({});

dv/dt = g - (k/m)v

Where g is the acceleration due to gravity, m the person's mass, and k is a constant depending on the physical properties of the parachute.

Question: How does this equation physically make sense? Where does the variables from the ride hand side come from?
