What us pulling force

  1. PP system - Ktrans = Fnet * rcm

  2. Real system -

Ktrans + Krot = W

½ m(vf² - vi²) + ½ I (wf² - wi²) = F * d

(solve for F)

If I is not given

  • I disk = ½ MR²

  • I points = 2 Ip = 2(MR²)

  • Total = ½ MR² + ½ ML²

What is final omega

  1. Ktrans = Fnet * rcm

  2. Real system =

Ktrans + Krot = Wreal

Fd + ½ I (wf² -wi²) = F(d+s)

solve for wf
