A particle in S.H.M. is described by the displacement function 
. If the initial (t = 0) position of the particle is 1 cm and its initial velocity is 
. The angular frequency of the particle is 
, then it's amplitude is
The displacement of a particle moving in S.H.M. at any instant is given by 
. The acceleration after time 
is (where T is the time period)
The displacement of an oscillating particle varies with time (in seconds) according to the equation y (cm) = sin 
. The maximum acceleration of the particle is approximately
A particle has simple harmonic motion. The equation of its motion is 
, where x is its displacement. If the displacement of the particle is 3 units, then it velocity is
If the displacement of a particle executing SHM is given by 
in metre, then the frequency and maximum velocity of the particle is
