Mass on a Spring: An object attached to an ideal spring oscillates with an angular frequency of 2.81 rad/s. The object has a maximum displacement at t = 0.00 s of 0.232 m. If the force constant (spring constant) is 29.8 N/m, what is the potential energy stored in the mass-spring system when t = 1.42 s?

A. 0.350 J
B. 0.256 J
C. 0.329 J
D. 0.399 J
