TEACHER NOTES

ISSUES RELATED TO THE PROBLEM

Prerequisites

Algebra, circumference of a circle; (polar coordinates in calculus provides an optional approach.)

Time allotment - time management

Expectations

Some students may need hints to Problem 2 such as: (1) what's the spindle speed when the radius is X? or Y?

Future payoffs

Extensions

A much harder problem is to determine the tape driver speed as a function of time. Offer as a challenge problem.
