Question

A particle executing simple harmonic motion has an amplitude of 1m and a time period of 2 seconds. At t=0, net force on the particle is 0. The equation of displacement of the particle isA. X=sin (πt)B. X=cos (πt)C. X=sin (2πt)D. X=cos (2πt)

Answer 1

thus the net force on particle is zero which implies acceleration is zero

and

acceleration is 0 only at mean position

so the eqn ll be

X = 1 sin (πt + 0)

w=2π/T

phase angle is O bcz the particle is at mean position
