Homework Answers
here,
mass of earth , M = 5.98 * 10^24 kg
radius , r = 6.371 * 10^6 m
let the altitude above the earth surface be A
the gravity acceleration , a = G * m /(r + A)^2
7.3 = 6.67 * 10^-11 * 5.98 * 10^24 /(6.371 * 10^6 + A)^2
solving for A
A = 1.02 * 10^6 m = 1020 km
the altitude above the earth surface is 1020 km

A planet has a gravitational acceleration on its surface of 0.5 times Earth's gravitational acceleration on its surface. The planet's radius is two times Earth's radius. What is the mass of the planet, in terms of Earth masses, ME? Hint: Write equations for the gravitational acceleration on the surface of the planet and on Earth's surface in terms of their respective masses and radii. Then write the relationships between Earth's and the planet's gravitational accelerations, and between the Earth's and...

1. For the earth, an estimate of the variation of pressure with altitude above the surface of the earth is made for a gas of molecular weight, M, assuming the atmosphere is isothermal, the variation of g with altitude is negligible, and that the atmosphere behaves like an ideal gas. A significant error in this estimate arises from the assumption that the temperature of the atmosphere, T, is isothermal instead of decreasing with altitude. This decrease with altitude y in...

(25 pts) Make a plot of the gravitational magnitude acceleration versus radius for a satellite in Earth orbit. The x-axis should be the orbital radius in units of Earth radii, from Earth's surface, 6,378 km, to 75,000 km. The y-axis should be the computed acceleration in units of m/s2. Be sure to label your plot.
