Chapter 15, Problem 89(choose chapter or problem)
A 3.0 kg particle is in simple harmonic motion in one dimension and moves according to the equation x (5.0 m) cos[(p/3 rad/s)t p/4 rad], with t in seconds. (a) At what value of x is the potential energy of the particle equal to half the total energy? (b) How long does the particle take to move to this position x from the equilibrium position?
