Question

For a body **rolling without slipping** on a flat surface with centre-of-mass velocity $v$, the **velocity of the topmost point** is:

Accepted Answer

C. $2v$

**Rolling:** $v_{	ext{cm}} = R\omega$.
**Top point:** $v_{	ext{cm}} + R\omega = 2v$.
**Bottom (contact) point:** $v_{	ext{cm}} - R\omega = 0$ (instantaneously at rest).

Answer

$0$

Answer

$v$

Answer

$v/2$
