You wish to put a 1000-kg satellite into a circular orbit 300 km above the earth’s surface. (a) What speed, period, and radial acceleration will it have? (b) How much work must be done to the satellite to put it in orbit? (c) How much additional work would have to be done to make the satellite escape the earth? In part (b) if we ignored the satellite’s initial kinetic energy due to the rotation of the earth. How much difference does this make? Suppose your personal spacecraft is in a low-altitude circular orbit around the earth. Air resistance from the outer regions of the atmosphere does negative work on the spacecraft, causing the orbital radius to decrease slightly. Does the speed of the spacecraft (i) remain the same, (ii) increase, or (iii)

Question
You wish to put a 1000-kg satellite into a circular orbit 300 km above the earth’s surface. (a) What
speed, period, and radial acceleration will it have? (b) How much work must be done to the satellite to
put it in orbit? (c) How much additional work would have to be done to make the satellite escape the
earth? In part (b) if we ignored the satellite’s initial kinetic energy due to the rotation of the earth. How
much difference does this make?
Suppose your personal spacecraft is in a low-altitude circular orbit around the earth. Air resistance
from the outer regions of the atmosphere does negative work on the spacecraft, causing the orbital
radius to decrease slightly. Does the speed of the spacecraft (i) remain the same, (ii) increase, or (iii)
