Drag

The data come from an experiment to determine how terminal velocity depends
on the mass of the falling object. A helium balloon was rigged with a small
basket and just the ballast to make it neutrally buoyant. Mass was then
added and the terminal velocity is calculated by measuring the time it took
to fall between two sensors once terminal velocity has been reached. Larger
masses were drop from higher heights and used sensors more widely spaced.

"Foundations and Applications of Statistics: an Introduction
using R" (R Pruim, published by AMS, 2017), a text covering
topics from probability and mathematical statistics at an advanced
undergraduate level.  R is integrated throughout, and access to all
the R code in the book is provided via the snippet() function.
