A simple harmonic oscillator consists of a block of mass 4.10 kg attached to a spring of spring constant 350 N/m. When t = 1.20 s, the position and velocity of the block are x = 0.127 m and v = 3.390 m/s.
(a) What is the amplitude of the oscillations? What were the
(b) position and
(c) velocity of the block at t = 0 s?
