A) \[120\,\,mm\,{{s}^{-1}}\]
B) \[113\,\,mm\,{{s}^{-1}}\]
C) \[115\,\,mm\,{{s}^{-1}}\]
D) \[125\,\,mm\,{{s}^{-1}}\]
Correct Answer: B
Solution :
\[\omega =2\,\,rad/{{s}^{-1}},\,\,y=20\,\,mm,\,\,a=60\,\,mm\] \[v=\omega \sqrt{{{a}^{2}}-{{y}^{2}}}\] \[=\sqrt{{{(60)}^{2}}-{{(20)}^{2}}}\] \[=113\,\,mm/{{s}^{-1}}\]
