This is an interactive homework problem for introductory physics relating Newton's Second Law and gravitational acceleration.  It features a block at rest atop an incline, with angle of incline and ramp length given.  Students must determine the time required for the block to reach the bottom.   A user-activated "help" sequence is provided for each step of the problem-solving, from conceptual analysis through quantitative calculation.  Immediate feedback is received for both correct and incorrect responses. This resource is part of a larger collection of interactive problems for introductory physics. See Related Materials for a link to the full collection.
Editor's Note: We like this problem because it gives tips on finding the optimal coordinate system for solving the problem. To quote the author, " it is often worth your time to stop and think which directions are 'natural'. For example, the problem may have directions with no forces. This means that there is no acceleration in these directions. A problem that starts out 2-dimensional then turns out to really only have 1 dimension that matters."
