A particle moving with simple harmonic motion has a maximum displacement of +12.0 cm. The particle moves from its maximum positive to its maximum negative displacement in 2.25 seconds. The motion starts at t=0 when the dispacement is x = =12.0 cm. Calculate time for the particle to move directly to x = -6.00 cm.
