Aspring is mounted horizontally, with its left end fixed. a spring balance attached to the free end and pulled toward the right indicates that the stretching force is proportional to the displacement, and a force of 6.0 n causes a displacement of 0.030 m. we replace the spring balance with a 0.50 kg glider, pull it 0.020 m to the right along a frictionless air track, and release it from rest. (a) find the force constant k of the spring. (b) find the angular frequency w, frequency f, and period t of the resulting oscillation.
