A force F acts to the right on a 6.4 kg block. A 3.43 kg block is stacked on top of the 6.4 kg block and can slide on it with a coefficient of 1. 40.72541 2. 22.0506 friction of u1 =0.2 between the blocks. Both pulleys are massless and frictionless. The string is also massless. Note the axle of the upper pulley is free to move so it will accelerate to the left as the 6.4 kg block accelerates to the right. Think carefully about the magnitude of that axle's acceleration. The axle of the lower pulley is fixed at the position shown. The table has a coefficient of friction of 3. 49.393639 O 4. 56.648308 5. 39.322021 O 6. 31.94706 O 7. 42.29855 H2 =0.19. The acceleration of gravity is 9.8 m/s O8. 48.740013 O 9. 32.937958 3.43 kg F O 10. 34.211868 6.4 kg 12 Find the force F required to accelerate the 6.4 kg block at 1.7 m/s. (Hint: How many frictional forces are on the 6.4 kg block?). Answer in units of N.
