Question

A meterstick (L = 1 m) has a mass of m = 0.235 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 You currently have s for this question.

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 You currently have 0 submissions for this question. Only 10 submission are allowed. You can make 10 more submissions for this question.

4)hangingmeterstick2 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?

7) Where is the angular acceleration of the meterstick a maximum? right after the string is cut and the meterstick is still horizontal when the meterstick is vertical – at the bottom of its path the angular acceleration is constant
