Implementasikan dua function untuk simulasi spring physics.

Function 1: simulateSpring(from, to, options)

• Parameter options: { stiffness, damping, mass }
• Menggunakan Euler integration dengan timestep dt = 1/60
• Mengembalikan array 5 posisi pertama dari simulasi (termasuk posisi awal)
• Setiap iterasi: acceleration = (-stiffness * (position - to) - damping * velocity) / mass, lalu velocity += acceleration * dt, lalu position += velocity * dt
• Bulatkan setiap nilai ke 4 desimal

Function 2: classifySpring(stiffness, damping, mass = 1)

• Hitung damping ratio: ζ = damping / (2 * Math.sqrt(stiffness * mass))
• Kembalikan "underdamped" jika ζ < 1, "critically-damped" jika ζ === 1, "overdamped" jika ζ > 1

Hint

• Euler integration: tiap step dt = 1/60, hitung acceleration = (-stiffness × (position - to) - damping × velocity) / mass.
• Update per step: velocity += acceleration × dt; position += velocity × dt. Simpan 5 posisi pertama (termasuk posisi awal).
• classifyDamping: hitung damping ratio ζ = damping / (2 × Math.sqrt(stiffness × mass)). ζ < 1 underdamped, ζ = 1 critically-damped, ζ > 1 overdamped.
