## Homework Statement

A 1.0 kg box on a horizontal frictionless surface is accelerated by attaching a 1.5 kg mass as shown in the diagram. What is the magnitude of acceleration of the box?(Remember, both boxes accelerate.)

## Homework Equations

F = ma

## The Attempt at a Solution

I drew a free body diagram of all the forces on the system.

The only thing I can calculate from here is the force of gravity on the 1.5 kg object.

Fg = mg

Fg = (1.5 kg) (-9.81m/s^2)

Fg = -14.7 N

Where do I go from here?
