Options:
A) 0.2047 rad/sec., 0.0314 m/sec
B) 0.2547 rad/sec., 0.314 m/sec
C) 0.1472 rad/sec., 0.06314 m/sec
D) 0.1047 rad/sec., 0.00314 m/sec
Show Answer
Answer:
Correct Answer: D
Solution:
$ \omega =\frac{2\pi }{T}=\frac{2\pi }{60}=0.1047\ rad/s $ and $ v=\omega r=0.1047\times 3\times {{10}^{-2}}=0.00314\ m/s $
