The escape velocity of Earth is approximately 11.2 kilometers per second (km/s) or about 33,000 kilometers per hour (km/h). This is the minimum velocity required for an object to escape Earth's gravitational pull and venture into space.

Calculating the amount of fuel required to reach escape velocity depends on several factors, including the mass of the spacecraft and its payload, as well as the specific impulse of the propulsion system. Specific impulse measures the efficiency of a rocket engine and is typically expressed in seconds. It represents the change in momentum per unit of propellant mass.

To determine the fuel requirements, we need more specific information about the spacecraft and its propulsion system. However, it's worth noting that reaching escape velocity typically requires a substantial amount of fuel, as a significant amount of energy is needed to overcome Earth's gravitational pull.

As for the time required to reach escape velocity, it depends on the acceleration provided by the propulsion system. Assuming a constant acceleration, the time can be estimated using the formula:

t = v / a

where: t is the time, v is the velocity (escape velocity), and a is the acceleration.

Keep in mind that this estimate does not take into account various factors such as atmospheric drag, the need for staging (multiple rocket stages), and the practical limitations of rocket technology.
