There is no friction at all and this is a pulley system. The pulleys and string are mass-less. The numbers correspond to the block weight (ex: 3 = 3kg).
F = ma
The Attempt at a Solution
From my solutions guide, it seems that the acceleration of block 3 is not equal to the other two blocks. I do not understand this. They are all connected by the same string and therefore are influenced by the same force of tension.
