For a cylinder rolling without slipping, the point touching the ground has velocity:
ATwice the centre's
BExactly zero
CAt its maximum
DHalf the centre's
Answer & Solution
Correct answer: B. Exactly zero
1. No slipping means no sliding at the contact.
2. The contact point is momentarily at rest.
3. So its velocity is zero.
