Показать описание
The figure shows a system consisting of (i) a ring of outer radius \( 3 R \) rolling clockwise without slipping on a horizontal surface with angular speed \( \omega \) and (ii) an inner disc of radius \( 2 R \) rotating anti-clockwise with angular speed \( \omega / 2 \). The ring and disc are separated by frictionless ball bearings. The system is in the x-z plane. The point \( \mathrm{P} \) on the inner disc is at a distance \( \mathrm{R} \) from the origin, where OP makes an angle of \( 30^{\circ} \) with the horizontal. Then with respect to the horizontal surface.
(A) the point \( \mathrm{O} \) has a linear velocity \( 3 R \omega \hat{\mathrm{i}} \).
(B) the point \( P \) has a linear velocity \( \frac{11}{4} R \omega \hat{i}+\frac{\sqrt{3}}{4} R \omega \hat{k} \)
(C) the point \( P \) has a linear velocity \( \frac{13}{4} R \omega \hat{i}-\frac{\sqrt{3}}{4} R \omega \hat{k} \)
(D) the point \( P \) has a linear velocity
\( \left(3-\frac{\sqrt{3}}{4}\right) R \omega \hat{i}+\frac{1}{4} R \omega \hat{k} \)
(A) the point \( \mathrm{O} \) has a linear velocity \( 3 R \omega \hat{\mathrm{i}} \).
(B) the point \( P \) has a linear velocity \( \frac{11}{4} R \omega \hat{i}+\frac{\sqrt{3}}{4} R \omega \hat{k} \)
(C) the point \( P \) has a linear velocity \( \frac{13}{4} R \omega \hat{i}-\frac{\sqrt{3}}{4} R \omega \hat{k} \)
(D) the point \( P \) has a linear velocity
\( \left(3-\frac{\sqrt{3}}{4}\right) R \omega \hat{i}+\frac{1}{4} R \omega \hat{k} \)
