Yep, that was it. Thank you!

When the particle hits the disc it will begin rotating in the clockwise direction, that's why it's negative. As for the calculations: Ip = mr² = 0.186 Id = 3MR²/2 = 0.799 Ip + Id = 0.985 Ip * vR / Ip + Id = 10.6 If I use mVR = (Ip+Id)wf (as suggested by someone) I get 17.8... but shouldn't I...

Hi, I have the following problem: A homogeneous disc with M = 1.78 kg and R = 0.547 m is lying down at rest on a perfectly polished surface. The disc is kept in place by an axis O although it can turn freely around it. A particle with m = 0.311 kg and v = 103 m/s, normal to the disc's surface at...

Hey, so I have the following problem: I'm trying to prove that the limit doesn't exist (although I'm not sure if it does or not) so: along y=mx -> x=y/m: , which is 0 for all k≠0. along y^n it's the same and I'm not sure what I should do next. Could I set x = sin(y)? If I can, then the limit...
