A 5.10 kg object on a horizontal frictionless surface is attatched to a spring with spring constant 880 N/m. The object is displaced from equilibrium 50.0 cm horizontally and given an initial velocity of 8.9 m/s back toward the equilibrium point.

__ Hz
(b) What is the initial potential energy of the block-spring system?
__ J
(c) What is the initial kinetic energy?
__ J
(d) What is the amplitude of the oscillation?
__ m
