(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Three blocks are in contact with one another on a frictionless, horizontal surface as shown in Figure P4.43. A horizontal force vector F is applied to m1. Taking m1 = 2.00 kg, m2 = 3.00 kg, m3 = 5.00 kg, and F = 16.0 N, draw a separate free-body diagram for each block. (Do this on paper. Your instructor may ask you to turn in this work.)

I already answered parts a and b, i just need help with c:

(c) Find the magnitude of the contact forces between the blocks.

m1 and m2 ________ N

m2 and m3 ________ N

2. Relevant equations

i know that i need to use newton's third law of an object acting upon another object.

F = ma

3. The attempt at a solution

i tried doing F(m2/m1 + m2) for the first one and got 12, however the answer was wrong and the online program i have to use to turn it in says i was within 10% of the correct answer.

so now i'm stuck and don't know what to do.
