An unmanned spacecraft of mass 547 kg, is in a circular orbitaround the earth, observing the earth's surface from an altitude of52.8 km.
A. What is the orbital speed of the spacecraft?
B. What is the period of the spacecraft's orbit?
C. What is the escape velocity of the spacecraft?
D. To the dismay of scientists, an electrical fault causes anon-board thruster to fire, decreasing the speed of the spacecraftby 21m/s. If nothing is done to correct its orbit, with what speedwill the spacecraft crash into the earth's surface?
