This Demonstration depicts a two-block problem; it assumes the value of the acceleration due to gravity, , to be 9.8 . The masses of the blocks are indicated by their shade of blue.


One block, of mass , rests on a smooth horizontal surface and is attached to a cord of negligible mass with tension . The normal force acts on this block.

The other block, of mass , hangs vertically off the edge of the surface and is attached to the other end of the cord.

What is the acceleration, , of the blocks?
