Alright, I'm stuck on this problem. Two metal disks, Radius 1 = 2.5cm, Mass 1 = 0.8kg and Radius 2 = 5.0cm, Mass 2 = 1.6kg are wielded together and mounted on a frictionless axis through their common center. The first part asked what is the total moment of inertia of the two discs, which I...

Hey - thanks a lot for the help. Those are the same equations as what I was getting albeit one difference, and looking at the problem I thought "wow, this one's easy." yet I couldn't get any solutions. I see what I was doing wrong now. Instead of the velocities, Va and Vb, I was using their...

Ok, this is probably the simplest problem I was assigned out of an intro physics course and simply cannot figure out how to go about it. Hockey Puck B at rest is struck by puck A, which was traveling at 40.0m/s in the +x direction. After they hit, A is deflected 30 degrees above the x axis...
