A uniform rod has a mass of 2.86 kg and has a length of 1.49 m. It is hinged to a wall by a pivot at one end and is held in a horizontal position by a light vertical string attached to the other end as shown. wall string pivot rod (a) Calculate the magnitude of the tension in the string. N° (b) The string is now cut. Ignore the mass of the string. Calculate the magnitude of the angular acceleration (in rad/s2) of the rod about the pivot point just after the string is cut. rad/s?
