Force and acceleration question

[physics_geek]

Homework Statement

A force F applied to an object of mass m1 produces an acceleration of 3.20 m/s2. The same force applied to a second object of mass m2 produces an acceleration of 1.00 m/s2.
(a) What is the value of the ratio m1/m2?


(b) If m1 and m2 are combined, find their acceleration under the action of the force F.

Homework Equations

f=ma m1a1=m2a2

The Attempt at a Solution

i figured the out part a...the ratio to m1 to m2 is .313

i don't understand part b..i know if you add m1 and m2..the resulting acceleration should be smaller

Hi physics_geek!

It just means what is the acceleration if the same F acts on a mass of (m1 +m2)

k thnx
figured it out!
