## Website Detail Page

This is an interactive homework problem for introductory physics students relating to uniform circular motion.  Two rocks of known mass are tied at opposite ends of a .19m string.  A second string measuring .14m is tied to one rock.  The pair of rocks is then spun in a circle.  Students must determine the tension of the string connected to the rock closest to the center of the circle.

A user-activated "help" sequence is provided for each step of the problem-solving, including conceptual analysis and quantitative calculations.  Immediate feedback is received for both correct and incorrect responses.  This item is part of a larger collection of interactive homework problems for introductory physics.  See Related items on this page for a link to the full collection.
