A Particle Is in Simple Harmonic Motion Along the X

question 46

Multiple Choice

A particle is in simple harmonic motion along the x axis. The amplitude of the motion is x_m. When it is at x = x₁, its kinetic energy is K = 5J and its potential energy (measured with U = 0 at x = 0) is U = 3J. When it is at x = -1/2x_m, the kinetic and potential energies are:

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