A) \[1.5\]rad \[{{s}^{-1}}\]
B) \[5.2\]rad \[{{s}^{-1}}\]
C) \[2.5\]rad \[{{s}^{-1}}\]
D) None
Correct Answer: B
Solution :
If rod is rotated about end A, then vertical component of velocity v of end A will be zero \[\therefore \,\,\,\omega =\frac{v\,\cos \,60{}^\circ }{l}=\frac{\sqrt{3\,v}}{2l}=\frac{\sqrt{3}\times 3}{2\times 0.5}=5.2\,rad\,\,{{s}^{-1}}\]You need to login to perform this action.
