How much time will a particle oscillating according to equation y = 10 sin (0.9 `pit`)m take to move from mean position to position of maximum displacement ?

Explanation

To find the time it takes for a particle oscillating according to the equation \( y = 10 \sin(0.9 \pi t) \) to move from the mean position to the position of maximum displacement, we can follow these steps:

### Step 1: Identify the angular frequency
The given equation is in the form \( y = A \sin(\omega t) \), where:
- \( A = 10 \) m (amplitude)
- \( \omega = 0.9 \pi \) rad/s (angular frequency)

### Step 2: Calculate the time period (T)
