If the length of the second's hand in a stop clock is 3 cm the angular velocity and linear velocity of the tip is

Explanation

To solve the problem, we need to find the angular velocity and linear velocity of the tip of the second's hand of a stop clock, given that the length of the second's hand is 3 cm.

### Step-by-Step Solution:

1. **Identify the Radius**:
The length of the second's hand is given as 3 cm. This length can be considered as the radius (r) of the circular motion.
\[
r = 3 \, \text{cm} = 3 \times 10^{-2} \, \text{m}
