A 2-kilogram block is attached horizontally to a spring on a frictionless surface, as shown above. The spring has a spring constant of 200 newtons per meter and negligible mass. The string is compressed 15 cm to the left. (A) Determine the speed of the block at the instant it goes through its equilibrium position.
(B)Determine the period of the block.
(C)Determine the frequency of the block.
(D) Where is the kinetic energy of the block at a maximum? Explain.
