**rotational dynamics rod--plz help!**

## Homework Statement

A thin rod of length

*l*and mass

*m*is fixed at a far ends by a free pivot and held from rotating with a string attached at 3/4

*l*and fixed toa ceiling. The moment of inertia of a thin rod about a far end is

*ml*

^{2}/3

a) what is the pivot point exerting on the rod

The rope is cut at t =0 seconds. at t =0 seconds find:

b) the angular acceleration of the rod.

c) the transverse acceleration of the rod's center of mass.

d) the transverse aceleration of point A (the far end of the rod)

e) the force exerted by the pivot point

picture is attached.
