Question

A disk rotating about its axis from rest acquites angular speed of

Answer 1

$\mathfrak{The\:Answer\:is}$

vA = Rωo; vB = Rω0, vc = (R/2)ω0

The disc will not roll

Angular speed of the disc = ωo

Radius of the disc = R

Using the relation for linear velocity, v = ωoR

For point A:

vA = Rωo; in the direction tangential to the right

For point B:

vB = Rωo; in the direction tangential to the left

For point C:

vc = (R/2)ωo in the direction same as that of vA

$\boxed{Hope\:This\:Helps}$
