A harmonic oscillator vibrates with amplitude of \( 4 \mathrm{~cm} \) and performs 150 oscillations in one minute.
\( \mathrm{P} \) If the initial phase is \( 45^{\circ} \) and it starts moving away from the origin, then the equation of motion is
(1) \( 0.04 \sin \left(5 \pi t+\frac{\pi}{4}\right) \)
(2) \( 0.04 \sin \left(5 \pi t-\frac{\pi}{4}\right) \)
(3) \( 0.04 \sin \left(4 \pi t+\frac{\pi}{4}\right) \)
(4) \( 0.04 \sin \left(4 \pi t-\frac{\pi}{4}\right) \)
