Four identical blocks each of mass m are arranged as shown on a frictionless surface. Block 1 is pushed w force F. The coefficient of friction between the blocks is large enough that the blocks do not slide with res to one another (so there is a friction between the blocks but no friction from the horizontal surface). We c neglect drag from the air. 4 3 1 2 Your friend draws the free body diagram on block 3. n2 on 3 fs,2 on 3 n4 on 3 FG,EE on 3 You are asked to evaluate their work and you start by making sure they have the right number of forces. tell your friend
