A transverse mechanical harmonic wave is travellling on a string. Maximum velocity and maximum acceleration of a particle on the string are `3m//s` and `90 m//s^(2)`, respectively. If the wave is travelling with a speed of `20 m//s` on the string, write wave function describing the wave. \

Explanation

To write the wave function for the given transverse mechanical harmonic wave traveling on a string, we can follow these steps:

### Step 1: Identify Given Values
We are given:
- Maximum velocity, \( V_m = 3 \, \text{m/s} \)
- Maximum acceleration, \( A_m = 90 \, \text{m/s}^2 \)
- Wave speed, \( v = 20 \, \text{m/s} \)
