**Really need help in finding the acceleration for "built" boxes.**

## Homework Statement

Small block 1 with mass m = 2.56 kg sits on top of large block 2 of mass M = 7.7 kg, and the pair sit on a frictionless, horizontal table. Between the blocks: the coefficient of kinetic friction is μk = 0.146, and the coefficient of static friction is μs = 0.203.

Now, suppose the force applied to block 1 has magnitude F = 22.6 N, which is greater than 6.79 N. Find the magnitude of the acceleration of each block.

→ magnitude of the acceleration of block 1 (top block)

→ magnitude of the acceleration of block 2 (bottom block)

## Homework Equations

→F = ma.

→ΣF_up = ΣF_down

→ΣF_left = ΣF_right

→Newtons' Laws of Motion

## The Attempt at a Solution

Drew the FBD [free body diagram] (see attachment) and can't seem find the way to approach the problem.
