Part A A mass is oscillating with amplitude A at the end of a spring. How far (in terms of A) is this mass from the equilibrium position of the spring when the elastic potential energy equals one third the kinetic energy? For related problem-solving tips and strategies, you may want to Express your answer as a multiple of amplitude A to three significant figures. view a Video Tutor Solution of Simple harmonic motion on an air track, I: Physical properties.
