1.5: The Falcon 9 rocket version 1.2 that Elon Musk calls the "Full Thrust" version has a total initial takeoff thrust of 7607 kN (kilo-Newtons, each of which is 1000 N) from its first-stage rocket engines at sea eve. The vehicle has a mass of 549.054 metric tons on takeoff (a metric ton is 1000 kg or 2200 lb, which turns out to be pretty close to an Imperial ton, which is 2000 Ib).

Many communication satellites are placed in a circular orbit around the Earth at a radius where the period (the time to go around the Earth once) is 24 hours. If the satellite is above some point on the equator, it stays above that point as the Earth rotates, so that as viewed from the rotating Earth the satellite appears to be motionless. That is why you see dish antennas pointing at a "fixed" point in space. (a) Calculate the radius...
