Add FBD if needed plz

le 2-m long bar AB with a mass of 2 kg, and of small cross section rotates In a verticall plane (x-z) about a horizontal axis (x) which passes through A. It accelerates uniformly from 20 rev/min to 30 rev/min in 5.0 s. after which the angular velocity remains constant. Initially bar is horizontl. a) What is the linear velocity of its mid point at the beginning and at t = 5.0 sec. V b) Find the normal and tangential components of the acceleration of the mid-point of the bar after 3 s acceleration begins. c) What is the magnititude and direction of angular acceleration of the bar after 5 seconds has passed. d) What is the maximun and minimum energy and location of B for these energies e) What is the total energy of the system at t = 5 s
