A3.00 kg object rests upon a frictionless, horizontal floor. the object is attached to a horizontal spring (of force constant k = 485 n/m) whose other end is anchored to a nearby wall. the object is pulled until it lies a distance xi = 4.85 cm from its equilibrium position (x = 0). the object is then released and undergoes simple harmonic motion.
