http://www.public.asu.edu/~gbadams/f06/F424.gif

Block1 = 2kg

Block2 = 3kg

Block3 = 4kg

What is the force on block 1 by block 2

2. Relevant equations

F=ma

3. The attempt at a solution

i know this is easy but i cant figure it out.

i found the acceleration of the 3 blocks

8=9a

a=0.889

i know the net force on block 1 is 0.889(2kg) = 1.78

I know the answer is 6.22N but i am not sure how to find it.

any help would be great.

thank you
