A simple harmonic oscillator consists of a block of mass 4.20 kg attached to a spring of spring constant 194 N/m. When t = 3.00 s, the position and velocity of the block are x =+0.129 m and v = +3.415 m/s.
1) What is the amplitude of the oscillations?
2) What was the position of the mass at t = 0s?
3) What was the velocity of the mass at t = 0s?
