Another common version of Atwood's machine found in nearly all high school physics courses. A block is placed on a tilted frictionless surface and connected by a string that runs over a massless pulley to a hanging mass. The blocks are released and allowed to accelerate.

In this problem we will use Newton's Laws (primarily Newton's 2nd Law), a system of equations and free body diagrams for each block in order to solve for an equation that describes the acceleration of the system. The solution will also determine whether the block on the hill will accelerate up or down the hill.
