## Homework Statement

Two boxes are in contact with each other, both different mases, and are both being pulled by an external force, F.

M1M2--------->F

I can calculate the acceleration of the system but the Question asks to calculate the force between the mases, ie newtons third law. If you can either draw me the FBD or solve the question that would be helpful. M1 = 1.2 X 10^-3 kg, m2 = 0.147kg, F = 0.6 N

## Homework Equations

F = ma

## The Attempt at a Solution

a system = net force/total mases in system

= 0.6 N (1.2 X 10^-3 Kg + 0.147 kg)

= 4.048 m/s^2

FBD:

Fn

^

Fc <----m1---->F

Fg (Where Fc is the force between the two objects)

Fn

m2----->F

----->Fc

Fg
