Example #1 A spring is mounted horizontally, with its left end held stationary. By attaching a spring balance to the free end and pulling toward the right, we determine that the stretching force is proportional to the displacement and that a force of 6.0 N causes a displacement of 0.030 m . After allowing the spring to relax to its original length, we remove the spring balance and attach a 0.50-kg body to the end, pull it a distance of 0.020 m , release it, and watch it oscillate. What is the spring constant and its angular equency frequency. 00 applied F N k r a d 1 200 k x m = = 20 m s ω = = Test #1 A spring is mounted horizontally, with its left end held stationary.
