Achieving Ballistic Velocity (The Tsiolkovsky Cow Equation)
The **Rocket Equation** is brutal:
`Δv = Isp * g₀ * ln(m₀ / m_f)`
Where:
* `Δv` = Change in velocity needed (`11,186 m/s` for escape).
* `Isp` = Specific impulse (`~360 s` for CH4/LOX).
* `g₀` = Gravity (`9.81 m/s²`).
* `m₀` = Initial mass (cow + engines + LOX + methane).
* `m_f` = Final mass (just… cooked cow?).
**Assumptions:**
* Engine mass: `300 kg` (mini-Raptor).
* LOX mass: **5x** methane mass (rocket ratio).
* Methane stored: `500 kg` (we’re pumping hard).
* `m₀ = 700 (cow) + 300 (engine) + 500 (CH₄) + 2,500 (LOX) = 4,000 kg`.
* `m_f = 700 kg` (cow, assuming engines/tanks detach).
**Calculation:**
`Δv = 360 * 9.81 * ln(4,000 / 700)`
`= 3,531.6 * ln(5.71)`
`= 3,531.6 * 1.74`
`= ~6,150 m/s`.
**Result:** **6,150 m/s < 11,186 m/s**.
→ **Verdict:** Suborbital cow. Maximum apogee: **~1,000 km** (a very high moo).
→ **Impact Velocity:** **~3-4 km/s** (kinetic energy = 0.5 * 700kg * (3,500m/s)^2 ≈ **4.3 gigajoules**).
→ **Effect:** Creates a **10m wide crater**, vaporizing the cow and any nearby farmers. A true “pasture bomb.”
