A Particle Is in Simple Harmonic Motion Along the X

question 40

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 = 5 J and its potential energy (measured with U = 0 at x = 0) is U = 3 J.When it is at x = -1/2 x_m, the kinetic and potential energies are:

• A)K = 6 J and U = 2 J
• B)K = 6 J and U = -2 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
