A simple harmonic oscillator consists of a block of mass 4.30 kg attached to a spring of spring constant 210 N/m. When t = 1.60 s, the position and velocity of the block are x = 0.104 m and v = 3.580 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? (a) Number Units (b) Number Units (c) Number Units
