Kinetic Friction of Blocks: Mass M & 2M, 0.500m/s^2

[JUniTo24]

When the three blocks are released from rest, they accelerate with a magnitude of 0.500m/s^2.Block 1 has mass M, block 2 has 2M.What is the coefficient of kinetic friction between block 2 and the table?

Take each mass in turn, analyze the forces on it, and apply Newton's 2nd law. You'll get three equations that you can solve together to find μ.
