a) What is the horizontal distance of the center of gravity of the person-ladder system from the point where the ladder touches the ground?  b) What is the torque about the rotation axis shown in the figure (point B) computed by taking the total weight of the person plus ladder acting at the center of gravity? Express your answer to three significant figures and include the appropriate units. c) How does the result in part B compare to the sum of the individual torques τ_1 = 270 N⋅m and τ_2= 800 N⋅m for the weight of the person and the weight of the ladder? (Answer in part B is equal to the sum of individual torques or Answer in part B is not equal to the sum of individual torques)
