A body describes simple harmonic motion with an amplitude of 5 cm and a period of `0.2s`. Find the acceleration and velocity of the body when the displacement is (a) 5cm, (b) 3cm, (c) 0 cm.

Explanation

To solve the problem, we will use the formulas for acceleration and velocity in simple harmonic motion (SHM). The given parameters are:

- Amplitude (A) = 5 cm = 0.05 m
- Time period (T) = 0.2 s

### Step 1: Calculate Angular Frequency (ω)
The angular frequency (ω) is given by the formula:
\[
