A superhero tries to move a massive odd-shaped boulder. The boulder can be considered a composite volume with masses of mA = 7300 kg and mB = 3240 kg. Let the coefficients of sliding and non-sliding friction between the boulder and the ground beµs = 0.24 and µk = 0.35, respectively. Answer the following questions assuming that the superhero's resultant force P strikes the boulder at a height of h = 1.5 m above the ground and at an angle from the horizontal. If the angle is α = 30°... A. Determine the magnitude of the force P required for sliding to impend if no tipping occurs. B. Determine the magnitude of the force P required for tipping to occur in the absence of slippage. C. If the superhero's resultant force P = 30kN, describe the motion of the boulder (not moving, tipping, about to tip, etc.).

SAMPLE PROBLEM
A superhero tries to move a massive odd-shaped boulder. The boulder can be considered a composite volume with masses of mA = 7300 kg and mB = 3240 kg. Let the coefficients of sliding and non-sliding friction between the boulder and the ground beµs = 0.24 and µk = 0.35, respectively. Answer the following questions assuming that the superhero's resultant force P strikes the boulder at a height of h = 1.5 m above the ground and at an angle from the horizontal.
If the angle is α = 30°...
A. Determine the magnitude of the force P required for sliding to impend if no tipping occurs.
B. Determine the magnitude of the force P required for tipping to occur in the absence of slippage.
C. If the superhero's resultant force P = 30kN, describe the motion of the boulder (not moving, tipping, about to tip, etc.).
