Problem

During an ascent in a space elevator, an astronaut of mass

65\,\text{kg}

is at an altitude of

200\,\text{km}

above Earth’s surface while the cabin accelerates upward at

1.5\,\text{m s}^{-2}

. Using

R_E = 6400\,\text{km}

and surface value

g = 9.8\,\text{m s}^{-2}

, calculate the apparent weight recorded by the cabin floor at that instant.
