A simple harmonic oscillator consists of a block of mass 1.70 kg attached to a spring of spring constant 390 N/m. When t = 2.30 s, the position and velocity of the block are x = 0.173 m and v = 2.830 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?

i got part a to be .255 m but im not sure how to do b or c
