… give the lengths names …

Hi myoplex11! :smile:

The first thing to do is to give the lengths of the cords letters, such as a and b.

I haven't seen the picture yet, so I don't even know if there's two blocks, but I assume a + b is a constant, so you can call that c, and then eliminate b by putting b = c - a.

Then you use your F = mx´´ equation to get an equation in a´´. :smile:
