An object of mass 1.26 kg attached to a spring of force constant 5.38 N/cm is set into oscillation by extending the spring 26.3 cm and giving the object a velocity of 3.72 m/s toward the equilibrium position of the spring. Using the results obtained in Problem 9, calculate (a) the amplitude and (b) the phase angle of the resulting simple harmonic motion.
