## Homework Equations

Ff=μFn,

F=ma

## The Attempt at a Solution

(a) The blocks can have the same acceleration due to static friction.

consider the 2 blocks on the left: Ff=fmg

then consider the 2 blocks on the right: Ff is also fmg? I am rather confused at this point... how does M come into the equation? because the answer for part (a) is 2(M+m)/(M+2m)f. There is no g anywhere in the equation, though from the equation, friction is to the normal, which is mg?

THank you!
