**Calculus**Level 2

A particle is executing 1D motion. Its acceleration as a function of time is given by \(a=-Aw^{2}\sin(wt)\). At time \(t\), the magnitude of displacement from the mean position, velocity, acceleration are equal. Then find the value of \(t\).

**Details and assumptions:**

- At maximum acceleration(magnitude), velocity is 0
- At maximum velocity, displacement is zero
- \(w\) is angular frequency
- 'A' a is constant of appropriate dimensions
