to an ideal spring ma 5.4.1. A 1.50-kg, frictionless block is attached to an ideal with force constant 600 N/m. At t=0 the spring is neither stra nor compressed and the block is moving in the positive directie 8.0 m/s. Find (a) the amplitude and (b) the phase angle. (c) w an equation for the position as a function of time. 5.4.2. A harmonic oscillator has angular frequency w and amplituda! A. (a) What are the magnitudes of the displacement and velocity whes the elastic potential energy is equal to the kinetic energy? (Assume that U = 0 at equilibrium.) (b) How often does this occur in each cycle? What is the time between occurrences? (c) At an instant when the displacement is equal to A/2, what fraction of the total energy of the system is kinetic and what fraction is potential?
