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

A force of 32.68 N pushes and pulls to blocks as shown in the figure below. The vertical contact surfaces between the two blocks are frictionless. The contact between the blocks and the horizontal surface has a coefficient of friction of 0.24. The acceleration of gravity is 9.8 m/s2 .

(On a table) The weight of the first block is 4.3 kg. The force is pushing in the same direction as the table upon the first block. The second block weighs 8.6 kg. The force pulling this block, however, is at a 60 degree angle from the table.

The coefficient of friction is 0.24.

What is the magnitude a of the acceleration of the blocks?

Answer in units of m/s2.

2. Relevant equations

Fnet=ma

3. The attempt at a solution

I drew two free body diagrams. The first one has Force pushing from the left to the right, friction going in the opposite direction, natural force going up and w going down. The second has friction going from right to left, Force going from left to right at a 60 degree angle, w2 going down and natural force2 going up.

I'm confused, however, because of the fact that the second block isn't being pulled straight forward. I understand that this affects the net Force of block 2 but does it also affect the force that block one puts on block two and that block two puts on block one?
