A 250-g object attched to a spring oscillates on a frictionless table with a frequency of 4 Hz and an amplitude of 20 cm. Calculate the:
A) maximum potential energy of the system
B) displacement of the object when the potential energy is one half of the maximum
C) the potential energy when the displacement is 10 cm.
