(a) Number 0.571 A simple harmonic oscillator consists of a block of mass 4.70 kg attached to a spring of spring constant 140 N/m. When t = 2.00 s, the position and velocity of the block are x = 0.169 m and v = 3.050 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? Units (b) Number -3.87 Units (c) Number i 21.26 Units m/s 3 3 (a) Number 0.571 A simple harmonic oscillator consists of a block of mass 4.70 kg attached to a spring of spring constant 140 N/m.
