How high does a rocket have to go above the Earth's surface until its weight is 0.3 times its weight on the Earth's surface? The radius of the earth is 6.37 x 10^6 m and the acceleration of gravity is 9.8 m/s^2. Answer in units of km.
2. A rocket of mass m is fired vertically from the Earth, with an initial speed U. It rises to a height R/2 before falling back to Earth, where R is the radius of the Earth. Calculate U in terms of G, M (the Earth's mass) and R. The rocket is fired with the same initial speed, but this time at an angle 45° to the horizontal. Calculate its angular momentum J and total energy E, and use these to...
