A meterstick (L = 1 m) has a mass of m = 0.152 kg. Initially, it
hangs from two short strings: one at the 25 cm mark and one at the
75 cm mark.
1)
What is the tension in the left string?
N
2)
Now the right string is cut! What is the initial angular
acceleration of the meterstick about its pivot point? (You may
assume the rod pivots about the left string, and the string remains
vertical)
rad/s2
3)
What is the tension in the left string right after the right
string is cut?
N
4)
After the right string is cut, the meterstick swings down to
where it is vertical for an instant before it swings back up in the
other direction.
What is the angular speed when the meterstick is vertical?
rad/s
5)
What is the acceleration of the center of mass of the meterstick
when it is vertical?
m/s2
6)
What is the tension in the string when the meterstick is
vertical?
