PUSHING BLOCKS BASE Pushing Blocks 4 3 1 2 Four blocks EACH of mass m = 10 kg are arranged as shown in the picture, on top of a frictionless table. A hand touching block 1 applies a force of Fih = 90 N to the right. The coefficient of friction between the blocks is sufficient to keep the blocks from moving with respect to each other. What is the total force exerted on block 3 by block 2 ? F32net =
