Homework Help: Force and acceleration question

  1. Nov 8, 2008 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations
    f=ma m1a1=m2a2

    3. The attempt at a solution
    i figured the out part a...the ratio to m1 to m2 is .313

    i dont understand part b..i know if you add m1 and m2..the resulting acceleration should be smaller

    Hi physics_geek! :smile:

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