Force on Two Masses
Since F is the only net force acting on the two masses, it determines the acceleration of both:
The force F
_{2}
acting on the smaller mass may now be determined.
Note that by
Newton's third law
, the force F
_{2}
acts backward on m
_{1}
. Note that the net force acting on m
_{1}
is consistent with the above.

Force on Two Masses
Add friction
Application of
Newton's second law
to two masses.
For a force F=
N applied to two masses m
_{1}
=
kg and m
_{2}
=
kg which are in contact with each other, the acceleration is given by
=
m/s²
Then the force exerted on mass m
_{2}
can be determined.
