A meter-stick (L = 1 m) consists of a mass of m = 0.156 kg. Primarily it suspends from two short strings: one at the 25 cm mark and one at the 75 cm mark.
i) Determine the tension in the left string?
ii) Now the right string is cut! Find out the initial angular acceleration of the meter-stick regarding its pivot point? (You might suppose the rod pivots about the left string and the string remains vertical)
iii) Determine the tension in the left string right after the right string is cut?
iv) After the right string is cut, the meter stick move back and forth down to where it is vertical for an instant before it swings back up in the other direction. Determine the angular speed if the meter sticks is vertical?
v) Determine the acceleration of the center of mass of the meter stick if it is vertical?
vi) Determine the tension in the string if the meter stick is vertical?
