Physics - Rotation Question with Solution | TestHub

Consider the rolling motion of a circular disc as shown in the adjacent diagram. Velocity of point of contact $(P)$ is $v_P=v-\omega R=v-v=0$ $$[\because v=\omega R]$$ velocity of point ${}^{\prime }{S}^{\prime },v_S=v+\omega R=2V$ velocity of centre ' $O^{\prime },v_0=v-\omega (0)=V$ Velocity of a point ' $T$ at distance $R$ from $P$ is $V_T=\omega R={\mathrm{O}}_V$ Thus possible velocities are $v,2v$ and $0.$
