A particle is in simple harmonic motion
along the x-axis. The amplitude of the
oscillation is A and its period is T. If at t
= 0 the particle is at x = +A, then at t =
1.25T, the particle is:
O between x = 0 and x = +A and is
travelling toward x = -A
O between x = 0 and x = +A and is
travelling toward x = +A
O at x = 0 and is travelling toward x = -A
O between x = 0 and x = -A and is
travelling toward x = -A
