Physics · MOTION IN A PLANE

An insect trapped in a circular groove of radius \( 12\text{ cm} \) moves along the groove steadily and completes \( 7 \) revolutions in \( 100\text{ s} \). What are the angular speed \( \omega \) and the linear speed \( v \) of the insect? (Use \( \pi = 3.14 \))

1. A
   \( \omega = 0.22\text{ rad/s} \), \( v = 2.6\text{ cm/s} \)
2. B
   \( \omega = 0.88\text{ rad/s} \), \( v = 10.6\text{ cm/s} \)
3. C
   \( \omega = 0.44\text{ rad/s} \), \( v = 5.3\text{ cm/s} \)
4. D
   \( \omega = 0.44\text{ rad/s} \), \( v = 2.3\text{ cm/s} \)
