A body of mass 2 kg lying on a smooth surface is attached to a string 3 m long and then rotated in a horizontal circle making 60 rev/min. Calculate the centripetal acceleration.

Explanation

To solve the problem of calculating the centripetal acceleration of a body rotating in a horizontal circle, we can follow these steps:

### Step 1: Convert the angular velocity from revolutions per minute (rev/min) to radians per second (rad/s).

Given:
- Angular velocity, \( \omega = 60 \, \text{rev/min} \)

To convert revolutions per minute to radians per second, we use the conversion factor:
...
