VCRTAPE

Tape thickness and speed.

BRIEF ABSTRACT

It's easy to estimate how thick a piece of paper is by measuring a ream of 500 sheets. This (fairly easy) problem deals with estimating the tape thickness on a video cassette, and then asks for a function which represents the tape driver speed. The problem is accessible to precalculus students, but accuracy and modeling issues also make it an appropriate application of polar integration!
