<s>[INST] A body hangs from a spring with a spring constant of 100 N/m. If a 1.8 kg body is attached to the spring, the extensions are as follows:
- At equilibrium: 0.245 m
- At maximum displacement: 0.485 m
- At minimum displacement: 0.005 m
Using these data, calculate:
1) The angular frequency (ω)
2) The maximum and minimum displacement
3) The displacement as a function of time (x(t) =?[/INST]
