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.
