A 4.05 x 10-2-kg block is resting on a horizontal frictionless surface and is attached to a horizontal spring whose spring constant is 121 N/m. The block is shoved parallel to the spring axis and is given an initial speed of 8.65 m/s, while the spring is initially unstrained. What is the amplitude of the resulting simple harmonic motion?
