DR STRANGE · Answer

HI, Its conservation of angular momentum concept! I 1 f 1 =I 2 f 2 ............(1) moment of inertia of rod (stick) in this case is, I= ML 2 /3. L=lenth of rod(stick) I 1 =ML 2 /3 f 1 =f 0 the bottom third of the stick were cut ,final length = 2L/3 final mass =2M/3 I 2 =(2M/3)(2L/3) 2 /3 =8ML 2 /81 put all this values in (1) get f 2 =27f 0 /8 ans.
