An object moves in simple harmonic motion with amplitude 13 m and period 3 minutes. At time t= 0 minutes, its displacement d from rest is -13 m, and initially it moves in a positive direction.

, where t is measure in minutes.

Step-by-step explanation:

The statement consists in the construction of the motion function for a object experimenting a simple harmonic motion. The expression for simple harmonic motion is:

Where:

- Amplitude, in m.

- Angular frequency, in rad/s.

- Phase angle, in rad.

The angular frequency is:

The amplitude of the motion is 13 m and the phase angle is:

The position function for the object is:

, where t is measure in minutes.
