A weight is suspended from a spring and is moving up and down in a simple harmonic motion . At start , the weight is pushed up 12 cm above the resting position , and then released . After 26 seconds , the weight reaches again to its highest position Find the equation of the motion , and locate the weight with respect to the resting position after 25 seconds since it was released
