A circular disc rolls on a horizontal floor without slipping and the centre of the disc moves with a unifonn velocity v. Which of the following values the velocity at a point on the rim of the disc can have? |
|
Answer» v So, velocity at the POINT of contact, `v_(g) = v - omegaR = 0` Velocity at the top, `v_(l) = v + omegaR = 2v`  Velocity at a point on the rim of DISC,vr =v is POSSIBLE if v and `omegaR` are at 120°. Velocity at a point on the rim of disc, v R = -v is not possible because `-1 lecostheta le1`. |
