In Figure P5.46, the pulleys and pulleys the cord are light, all surfaces are frictionless, and the cord does not stretch. (a) How does the acceleration of block 1 compare with the acceleration of block 2? Explain your reasoning. (b) The mass of block 2 is 1.30 kg. Find its acceleration as it depends on the mass m1 of block 1. (c) What If? What does the result of part (b) predict if m1 is very much less than 1.30 kg? (d) What docs the result of part (b) predict if m2 approaches infinity? (e) In this last case, what is the tension in the cord? (f) Could you anticipate the answers to parts (c), (d), and (e) without first doing part (b)? Explain.

Two thieves want to steal a 1mx1mx1m Lazada Mystery Box worth of 1million pesos that is placed on a warehouse with a cemented floor. When they successfully break into the warehouse using a bobby pin they realize that they both cannot carry the 400 lb package, so they decided to push it out of the warehouse. If the untouched package and the cemented floor has a coefficient of friction of 0.400, what is the maximum amount of force they first need to exert in order to make the package move when they will: A) push the package with their hands 90 degree with the vertical wall of the box. B) push the package with their hands in 120 degree with the vertical wall of the package. C) When they decided to pull the box instead and their hands are in 120 degree with the top edge of the box.
