A 220 gram block hangs from a spring with spring constant16 N/m. At t=0 the block is 18 centimeter below the equilibrium point and moving upward with a speed of 122 cm/s.
a) Find the block's oscillation frequency?
b) Find the block's distance from equilibrium when the speed is72 cm/s?
c) Find the block's position at t=5 s?
