A simple harmonic oscillator consists of a block of mass 1.40 kg attached to a spring of spring constant 450 N/m.?

When t = 0.970 s, the position and velocity of the block are x = 0.164 m and v = 4.130 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?
