roblem 1: A simple harmonic oscillator is composed of a mass hanging from a spring. The mass of the hanging object is 400 g and the spring constant is 0.8 N/m at the time ? = 0 ?, the mass is 2cm above its equilibrium position. The amplitude of the oscillation is 5 cm. a) What is the initial phase? b) Find one of the times where the mass is located at 3cm above equilibrium. c) Find the kinetic and potential energies at ? = 1s. d) What is the maximum kinetic energy? Answers: 0.41 rad, 0.16 s, 6.36E(-5) J; 9.36E(-4) J, 1E(-3)

A spring mass system has a period of 2.4 us when its amplitude is 1.6 CM if the amplitude is tripled what will the numerical value of the period be state unit

A mass is attached to a 35 Newton/meter spring that is anchored to a wall. When the mass is displaced it undergoes simple harmonic motion. a) determine the period, Mass, amplitude, max velocity, and angular frequency of a solution b) sketch the corresponding position and acceleration graphs and put the appropriate numerical values on all axes c) what would happen to the quantities of amplitude was doubled? What physically causes the period to remain the same? d) determine the position, velocity, and acceleration of the mass at .30 seconds. Explain what the particles doing at that time
