This is an interactive homework problem for introductory physics students relating to vector addition.  Given a free-body diagram depicting three forces acting on an object, students are required to find the magnitude of the net force.  A user-activated "help" sequence is provided for each step of the problem-solving, from conceptual analysis through 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.
