A Particle Is in Simple Harmonic Motion Along the X

Multiple Choice

A particle is in simple harmonic motion along the x axis.The amplitude of the motion is x_m.At one point in its motion its kinetic energy is K = 5 J and its potential energy (measured with U = 0 at x = 0) is U = 3 J.When it is at x = x_m, the kinetic and potential energies are:

A) K = 5 J and U = 3 J
B) K = 5 J and U = -3 J
C) K = 8 J and U = 0 J
D) K = 0 J and U = 8 J
E) K = 0 J and U = -8 J
