AI Generated Solution

To explain why an object projected with a velocity greater than or equal to 11.2 km/s will not return to Earth, we can break down the explanation into clear steps: ### Step 1: Understanding Escape Velocity Escape velocity is the minimum velocity an object must have to break free from the gravitational pull of a planet without any further propulsion. For Earth, this velocity is approximately 11.2 km/s. ### Step 2: Kinetic and Gravitational Potential Energy For an object to escape Earth's gravity, its kinetic energy must be greater than or equal to the gravitational potential energy it has due to Earth's gravity. ...
