A body of mass 0.5 kg made to revolve in a horizontal circle of radius 3 m with a uniform speed of `12 mm/s` . Find its
(i) angular speed
(ii) frequency of revolution.
(iii) time period .
(iv) centripetal acceleration.

Explanation

To solve the problem step by step, let's break down each part of the question systematically.

### Given Data:
- Mass of the body (m) = 0.5 kg (not needed for calculations)
- Radius of the circle (r) = 3 m
- Linear speed (v) = 12 mm/s = 0.012 m/s (conversion from mm/s to m/s)

### (i) Find the Angular Speed (ω)
