We quote from the article,

“The following experiment involves a balloon, a stopwatch, and a measurement device such as a meter stick. . . .  The goals of the experiment include fostering student participation, solving differential equations, dealing with parameters, comparing theory with experiment, and writing a group report.

Students solve the differential equations analytically in each case (i) – (iii) and from the distance the balloon fell (known!) and the time it takes to strike the floor (known!) the parameters k  and r, the power of velocity in F(v) = kv^r in the differential equation, can be ascertained.
