Please answer the following question exactly
There are three main ways that are being considered as means for getting an object off the surface of the planet Earth and into outer space: The chemical method The "rail-gun" method The space elevator method The chemical method . This is what is currently used. In this method, you strap your space vehicle onto large tanks of some fuel that is used as a propellant by being shot out one end of a rocket. In this method, the main goal is to achieve what is known as "escape velocity". The "rail-gun" method . In this method, you build a structure similar to a railroad track upon which you accelerate your vehicle (usually in a direction parallel to the ground) until you achieve escape velocity. The space elevator method. In this method, a satellite is placed in "geo-synchronous" orbit above a particular spot on the surface of the Earth. When a satellite is in a geo-synchronous orbit, it appears to always be in the same spot above a particular part of the Earth. For this HIP 3 do the following: Using the Newton's Law of Universal Gravitation, calculate die escape velocity for an object of arbitrary mass m to escape the gravitational pull of the Earth starting from the surface of earth and from a geo-synchonous space station. For each of the three methods described above, list and discuss which of the below PH 2 11 concepts and equations most strongly apply to that method. Concepts covered in PH 211: Position, velocity and acceleration in one, two and three dimensions Force and acceleration F = ma Circular Motion and Centripetal Acceleration Action/Reaction Pairs Impulse and Conservation of Momentum Work and Conservation of Energy Enhancement: Choose one of the three methods and design your own way of escaping the Earth's gravity. Include diagrams, text, and relevant calculations with numbers. (Bonus points for creativity and design coolness).Explanation / Answer
Potential energy on the surface of earth = -GmM/R
To escape, this must be cancelled by the Kinetic energy = m*v*v/2
Equating, m*v*v/2 = GMm/R
v = sqrt(2GM/R) = 11.2 km/s
