A simple harmonic oscillator consists of a block of mass 3.30 kg attached to a spring of spring constant 390 N/m. When t = 2.10 s, the position and velocity of the block are x = 0.151 m and v = 2.850 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 i Units v (b) Number i Units v (c) Number i Units
