Question
What is the minimum escape velocity of rocket to be
launched into space?Solution
On the surface of the Earth, the escape velocity is about 11.2 kilometers per second 06.96 mi/s), which is approximately 34 times the speedof sound(Mach34) andseveral timesthemuzzlevelocity ofarifle bullet (up to 1.7 km/s). However, at 9,000 km altitude in "space", it is slightly less than 7.1 km/s. In physics,escapevelocityisthespeedatwhichthe kinetic energy plus the gravitational potential energy of an object is zero.
