Pulling a Weight: An object of mass 2 kg, resting on a frictionless table, is attached to the wall by a spring as in Fig. 4.1.1. A force of 8 nt is applied to the mass, stretching the spring and moving the mass 0.5 m from its equilibrium position. The object is then released.
(a) Find the resulting motion of the object as a function of time.
(b) Determine the amplitude, period, and frequency of the motion.
(c) At what time does the mass first pass through the equilibrium position? What is its velocity at that time?
