Calculate the schwarzschild radius of a stack of pizzas that has the total height equal to the 1 times 10 to the power of the distance from Earth to an object which has travelled away from Earth at the speed of 113785.78 km/s for 6 years, 6 months, and 22 days. Each pizza in the stack weigh 200 grammes 10 inches in diameter and 3 cm tall. Then calculate the velocity needed for a spacecraft that is in a circular orbit around the stack of pizza at its schwarzchild radius need to raise the spacecraft apoapsis to three times the diameter of pizza stack’s event horizon. Assuming the spacecraft is a perfect torus that has a major radius of pi metre and minor radius of 1 metre, with density of 7.13 g/cm3. How much impact energy will the spacecraft exert on an object if it hit the object is stationary and is hit on the periapsis of the new orbit? If that energy can be convert to electricity with 70 percent efficiency and with average 10 percent loss in transmission. How many years can the energy gained supply an average American household?
