The displacement of a particle executing SHM is given by X = 3 sin [2πt + π/4] , where 'X' is in meter and 't' is in second. The amplitude and maximum speed of the particle is
The displacement 'x' (in metre) of a particle of mass 'm' ( in kg) moving in one dimension under the action of force, is related to time 't' ( in sec) by, t = √x+3. The displacement of the particle when its velocity is zero, will be
