A simple harmonic oscillator consists of a block of mass 4.10 kg attached to a spring of spring constant 195 N/m. When t = 2.00 s, the position and velocity of the block are x = +0.129 m and v = +3.415 m/s. (a) What is the amplitude of the oscillations? (b) What was the position of the mass at t = 0 s? (c) What was the velocity of the mass at t = 0 s?
