This is an interactive homework problem relating to conservation of angular momentum.  A small block on a string travels in circular motion on a table top.  The string passes through a hole in the table's center, hence the circle radius can be shortened by pulling the string.  Given mass of the block, students must determine how much work is done as the circular path is decreased from radius .63 m to .51 m.  A user-activated "help" sequence is provided for each step of the problem-solving, from conceptual analysis through quantitative calculation.  To promote critical thinking, 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.
