Physics · MOTION IN A PLANE

For an insect moving in a circular groove of radius \( 12\text{ cm} \) with a constant angular speed of \( 0.44\text{ rad/s} \), what is the magnitude of its centripetal acceleration \( a_c \)?

1. A
   \( 1.2\text{ cm/s}^2 \)
2. B
   \( 5.3\text{ cm/s}^2 \)
3. C
   \( 4.6\text{ cm/s}^2 \)
4. D
   \( 2.3\text{ cm/s}^2 \)
