A superhero attempted to move a huge odd-shaped boulder shown. The boulder can be thought of as a composite volume with the masses mA = 7300 kg and mB = 3240 kg. Let µs = 0.24 and µk = 0.35 be the coefficients of sliding and non-sliding friction between the boulder and the ground, respectively. Answer the following questions assuming that the resultant force P from the superhero hits the boulder at a height of h = 1.5 m above the ground and an angle from the horizontal: 1. Which of the ff. best shows the force diagram for the boulder?
