still confused
I am sorry.
One of the problems is that this proffesor, while a good and helpful person, has used his own characters for the variables..ie "om" instead of w for omega, and "al" for angular acceleration. While i know he thinks he's helping, it is causing me great problems when i...

While i have done the work and believe i have followed the equations, I'm not confident of my answer as I don't understandt the relationship between the units I am using. While I am pretty sure KE shoudl be in...
Glad you asked
Glad you asked. I have asked myself the same equestion many times. While I am not a genius by any stretch of the term, I don't consider myself diffficult to teach either. Let's face it, most problems do not take but a few minutes if you know the needed concepts. Often you are...
The question is:
A solid disk with m=60.0kg and a diameter of 48.0cm is to be turned from rest through 12.0 revolutions in 6.00s. Calculate the torque required to accomplish this.
What I've got is this:
Tau=I*al(angular acceleration)
I=.5*m*r^2 .5*60.0kg*.240m^2=1.728kg*m^2...
