Ernest Hemingway Key West Home And Museum. The Ernest Hemingway Key West House, or as it is officially known The Ernest Hemingway Home and Museum, was where the famous author decided to put down roots. And what better place to set up camp than on the island of Key West, down in the amazing Florida Keys.
In physics, escape velocity is the minimum speed needed for an object to break free from the gravitational attraction of a massive body. The escape velocity from earth is about 40,270 km/h (25,020 mph).
The official name for this speed is called the escape velocity. If a spacecraft is launched from a pad on the surface of the earth with this speed or greater, it will escape the Earth's gravitational field. The escape velocity can be calculated from the Earth's mass, its radius, and Newton's gravitational constant G: v_esc=sqrt(2*G*M/R). It is assumed for that formula that air resistance doesn't slow down the spacecraft (a very wrong assumption).
