Three blocks on a frictionless horizontal surface are in contact with each other. A force F is applied to block A (mass mA).
(a) Draw a free body diagram for each block.
I've drawn it and it looks like this, but I'm not sure if I'm including everything.
F-->|mA|<--Force of mass B on A
downward force is mAg
Force of mass A on B-->|mB|<--Force C on b downward force mBg
Force of mass B on C-->|mC|
downward force mCg
I figured that there couldn't be a force going to the right of C because I couldn't explain where it would come from so I left it bare.
Critique/help is much appreciated.
