I am not in these courses right now, but am trying to grasp the concepts so it doesnt happen again.

currently I am trying determine the force acting into a reciever when a slender rod with a mass of .033KG rotates 15degrees in 60 seconds and comes to a complete stop. the radius of rotation is .2542m

my calculations:

Omega=(theta)/t

=15/60

=.25 <<--------is this correct?

with this I can determine my angular acceleration:

(alpha)=dw/dt

=.25/60

=.0042 rad/s²

not sure what calculation to goto next. I have tried the parallel axis, I have tried the KE equation... not sure which path to take. this is where it gets REALLY FOGGY!

this is about as much as I picked up in class as the rest of this process is a complete blur... any help would be GREATLY appreciated.
