Question

6. Two blocks rest in contact with one another on a table. Their masses are mi-2 kg and m2-4 kg. The coefficients of static and kinetic friction are push s-0.40 and k-0.25, respectively. You push horizontally to the right on block 1 as shown in the figure. m2 m1 For parts a and b, you are pushing the blocks at constant velocity a) With what force are you pushing on block 1? b) With what force is block 1 pushing on block 2? For parts c and d, the blocks start from rest. You begin pushing on the blocks with an increasing force until the blocks start to move. You now maintain the force that started the blocks moving. c) With is the acceleration of the blocks once they start moving? d) With what force is block 1 pushing on block 2?

    1) Figure 1 illustrates first and second blocks having respective masses Mi and M2. An ideal horizontal rope is connected between the blocks and both blocks are positioned on a horizontal smooth surface (i.e. no friction force is applied by the smooth surface onto either block). A horizontal pulling force having magnitude Fp is applied by an external agent onto the first block horizontally toward the left, which causes the 2-block system to speed up while traveling toward the left....
