## Homework Statement

I uploaded the question as an attached file.

## Homework Equations

Fz = mg , F = ma ,

## The Attempt at a Solution

The slope : x

Perpendicular to the slope: y

I thought the Y forces can be neglected because the normal force counters the y component of the gravitational force.

Fz,x = mg sinθ

Without an external force, Fz,x is the only force along the x-axis. So the acceleration a=F/m. This acceleration must be equal to the acceleration of the big block, so F=Ma = (mgsinθ)/m * M = Mgsinθ.

This seems logical to me but the answer book states a totally different answer: (m+M)gtanθ.

What did I do wrong?

Thanks in advance!
