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 im so confused since we only only use V in circular motion, So I dont 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??
