A 140 g block hangs from a spring with spring constant 8.0 N/m. At t=0 s the block is 16 cm below the equilibrium point and moving upward with a speed of 89 cm/s. What are the block's oscillation frequency? What is the block's distance from equilibrium when the speed is 36 cm/s? What is the block's position at t=1.0 s?
