A particle of mass 0.1 kg is executing SHM of amplitude 0.1 m. When the particle passes through the mean position, its K.E. is 8 × 10–3 J. The equation of motion of the particle, when the initial phase of oscillation is 45o, is
  1. \(y=0.1 \sin \left(3 t+\frac{\pi}{4}\right)\)
  2. \(y=0.1 \cos \left(3 t+\frac{\pi}{4}\right)\)
  3. \(y=0.1 \sin \left(4 t+\frac{\pi}{4}\right)\)
  4. \(y=0.1 \cos \left(4 t+\frac{\pi}{4}\right)\)

Answer

(C) y=0.1 (4 t+ 4 )
