Understanding Escape Velocity
The escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a celestial body without any additional propulsion. For Earth, this velocity is approximately 11.2 km/s.
Given Conditions
- Mass of the new planet (M) = 9 times the mass of Earth (Me)
- Radius of the new planet (R) = 2 times the radius of Earth (Re)
Escape Velocity Formula
Escape velocity (Ve) can be calculated using the formula:
Ve = sqrt((2 * G * M) / R)
Where:
- G is the gravitational constant
- M is the mass of the planet
- R is the radius of the planet
Calculating New Escape Velocity
1. Substituting the values:
- Mass of the new planet: M = 9 * Me
- Radius of the new planet: R = 2 * Re
2. Plugging into the formula:
Ve = sqrt((2 * G * (9 * Me)) / (2 * Re))
3. Simplifying:
- This simplifies to: Ve = sqrt((9 * G * Me) / Re)
4. Relating to Earth's escape velocity:
- Since Ve(Earth) = sqrt((2 * G * Me) / Re), we can express the new escape velocity in terms of Earth's escape velocity.
5. Final Calculation:
- The new escape velocity becomes: Ve(new planet) = sqrt(9) * Ve(Earth) = 3 * Ve(Earth) = 3 * 11.2 km/s ≈ 33.6 km/s.
Conclusion
Thus, the minimum velocity required by a rocket to escape the gravitational pull of this new planet is approximately 33.6 km/s.
