This is an interactive homework problem for introductory physics students relating to Newton's Second Law.  Inside an accelerating car, a ball of known mass hangs from a string.   Given the string displacement from the vertical, the student must determine the magnitude of the car's acceleration.  A user-activated "help" sequence promotes understanding of this situation relative to positions both inside and outside the car.  Included are a step-by-step conceptual analysis, free-body diagrams, and explanation of math applications.  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.
