answer : maximum acceleration is 0.5 m/s²
explanation : standard equation of particle executing simple harmonic motion is given by,
where A is amplitude, is angular frequency and is phase difference.
comparing both equations,
we get, A = 2m , = 0.5 rad/s
we know, maximum acceleration of particle is
= (0.5)² × 2 m/s²
= 0.5 m/s²
hence, answer is 0.5 m/s²
