ICP 17 Coulomb Damping 1. Given m=2 kg, k=10,000 N/m, x =0.03 m, the vibration response is shown here (see this Google Sheets for data and detailed plot) (Important! This plot includes the nonexistent motion beyond the instant when the box has come to a halt!) 2. Determine w, (estimate from loss plot or data), and 3.
