Speed of blocks connected by pulley after moving 2.70cm

[TinaChan90]

As shown in the figure , block A (mass 2.20kg ) rests on a tabletop. It is connected by a horizontal cord passing over a light, frictionless pulley to a hanging block B (mass 2.27kg ). The coefficient of kinetic friction between block A and the tabletop is 0.344.

After the blocks are released from rest, find the speed of each block after moving 2.70cm

Asking for V.

And I am so confused since we only only use V in circular motion, So I don't even know how to set it up

Are you familiar with energy methods, Newton's laws, and / or the kinematic equations?? The velocity or speed is used quite often in Physics problems, so surely you must have seen it other than in circ motion problems, is that right??
