Homework Help: Physics

Posted by Physics on Sunday, July 12, 2009 at 12:06pm.

Ok I got a question I asked before except there are other parts that I didn't ask so here we go

Three blocks on a frictionless horizontal surface are in contact with each other

A force F is applied to block 1 (mass m1).

Draw a free-body diagram for each block

ok I did this

the acceleration of the system in terms of m1, m2, m3

I just found the acceleration of each block

a of m1 = m1^-1 F
a of m2 = (m1 + m2)^-1 F
a of m3 = (m1 + m2 + m3)^-1 F

did I do that right?

the net force on each block
how do I do this???

the force of contact that each block exerts on its neighbor

How do I do this???
