A block of mass 4 kg hangs from a spring constant `k=400(N)/(m)`. The block is pulled down through 15 cm below and released. What is its kinetic energy when the block is 10 above the equilibrium position.?

A block of mass 4kg hangs from a spring of force constant k = 400 N//m . The block is pulled down 15 cm below equilibrium and relesed. How long does it take block to go from 12 cm below equilibrium (on the way up) to 9cm above equilibrium ?
