2. Two blocks are sliding to the right across a horizontal surface, as Fig. 2 shows. In Case A, the mass of each block is 3.0 kg. In Case B, the mass of block 1 (the block behind) is 6.0 kg, and the mass of block 2 is 3.0 kg. No frictional force-acts on block 1 in either Case A or Case B. However, a kinetic frictional force of 5.8 N does act on block 2 in both cases and opposes the motion. For both Case A and Case B determine: Block 1 Block 2 Block 1 Block 2 m1 = 3.0 kg m2 = 3.0 kg m1 = 6.0 kg m2 = 3.0 kg %3D Case A Case B Fig. 2 (a) ( the magnitude of the forces with which the blocks push against each other. (b) the magnitude of the acceleration of the blocks. (c) ( ) the coefficient of kinetic friction between the horizontal surface and block 2.
