An object with mass 0.360-kg, attached to a spring with spring constant k = 10.0 N/m, is moving on a horizontal frictionless surface in simple harmonic motion of amplitude A = 0.0820 m. What is the kinetic energy of the object at the instant when its displacement is x = 0.0410 m? 0.042) O 2.46) 0.025 ) 9.86) 0.013)

The position of an object that is oscillating on a spring is given by the equation x = (0.232 m) cos((2.81 s-1)). 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? S 0.350 J 0.256) O 0.329 O 0.399 ) O 0.798)
