A particle suspended from a vertical spring oscillates 10 times per second. At the highest point of oscillation the spring becomes unstretched. A. Find the maximum speed of the block. B. Find the speed when the spring is stretched by 0.20 cm. Take `g=pi^2ms^-2`

Explanation

To solve the problem step by step, we will break it down into parts A and B as requested.

### Part A: Finding the Maximum Speed of the Block

1. **Identify the frequency and calculate the angular frequency (ω)**:
- Given frequency \( f = 10 \, \text{Hz} \).
- The angular frequency \( \omega \) is calculated using the formula:
\[
