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.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 its kinetic energy is 8 J, it is at:

A) x = 0
B) x = x₁
C) x = x_m/2
D) x = x_m/
E) x = x_m
