Two blocks are sliding to the right across a horizontal surface, as the drawing 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 (a) the magnitude of the forces with which the blocks push against each other and (b) the magnitude of the acceleration of the blocks.
