A) \[\frac{r{{\omega }_{0}}}{4}\]
B) \[\frac{r{{\omega }_{0}}}{3}\]
C) \[\frac{r{{\omega }_{0}}}{2}\]
D) \[r{{\omega }_{0}}\]
Correct Answer: C
Solution :
COAM about the contact point \[I{{\omega }_{0}}=I\omega +mvr\] \[m{{r}^{2}}{{\omega }_{0}}=m{{r}^{2}}\omega +mvr=2mvr\] \[\therefore \] \[v=\frac{r{{\omega }_{0}}}{2}\]You need to login to perform this action.
