A 1.44 kg monkey wrench is pivoted at oneend and allowed to swing as a physical pendulum. The period of itsmotion is 0.860 s, and the pivot is0.290 m from the center of mass of the wrench.a) What is the moment of inertia of the wrench?
If the wrench is initially pulled back to an angle of 0.600 radfrom the equilibrium position, (b) what is the angular speed of the wrench as it passes through the equilibrium position?
