An Object Attached to an Ideal Spring Oscillates with an Angular

question 48

Multiple Choice

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 $29.8 \mathrm {~N} / \mathrm { m }$ 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
