A) \[45\text{ }m{{s}^{-2}}\]
B) \[182\text{ }m{{s}^{-2}}\]
C) \[187m{{s}^{-2}}\]
D) \[192m{{s}^{-2}}\]
Correct Answer: A
Solution :
Given, angular velocity,\[\omega =15\text{ }rad/\text{ }s\] Time,\[t=0.270\text{ }s\] Radius,\[r=0.810\text{ }m\] Acceleration, \[a=\frac{v}{t}\] or \[a=\frac{r\omega }{t}\] \[[\because v=r\omega ]\] \[a=\frac{0.810\times 15}{0.270}\] \[=45m/{{s}^{2}}\]
