A 2m rod of mass 8 kg is supported by a (zero-friction) pin-joint at A. It is released from rest from the horizontal position. When the bar reaches the position as shown in the diagram,=60. Answer the following questions.1What is the moment of inertia (in kgm2) of the bar about A? (2 decimal places)What is the angular speed of the rod (in rad/s with 2 decimal places)?What isthe angular acceleration (in rad/s2)of the rod (with two decimal place)?What is the acceleration of point B (magnitude only in m/s2, with two decimal places)?
