Find the orbital speed of a satellite in a circular orbit 1870 km above the surface of the Earth. 1870km = 1.87e6 m I tried using the V^2=GMe/r and came up with 14.6 km/s which is wrong. I tried finding the velocity of earth 7.91 km/s and subtracting from the 14.6 km/s and still the answer is wrong. Am I using th
A woman astronaut weighs 120lb on earth-what does she weigh on mars?
Fscale-f = Fs Fn = mg f= coefficient of kinetic friction times Fn (normal force) coefficient of kinetic friction = Fs/mg What is meant by Fscale and Fs? These are lab calculations and in the lab I believe "Fscale" was measured by an actual scale used to pull a wooden block but I don't know what this scale is called.

Using the internet, I need to find the mass and radius of three of the nine planets in our solar system. Be sure that the masses are expressed in kilograms and the radii are expressed in meters. Using the data, calculate the gravitational acceleration on each of the three planets you selected. Note: With the masses measured
Using Newton's Universal Law of Gravity calculate the: (a) Force of attraction between the MOON and the EARTH [M sub E = 6.0 x 10 ^24 kg, M sub M = 7.4 x 10^22 kg], [R sub orbit = 3.84 x 10^8]. (b) From part a, calculate the centripetal acceleration of the Moon. (c) From part b, determine the angular speed omega of the Mo
A spherical balloon of radius 10.0 m has a mass of 600 kg when empty. If the balloon is filled with 1.0 atmospheres of helium gas, what is the mass of the largest cargo it could carry near the earth's surface to get off the ground: (a) Make a labeled diagram of the forces. (b) Use Archimedes principle to determine the buoyant
A helium filled balloon is tied to a 2.0 meter long, 0.050-kg string. The balloon is spherical with a radius of 0.40 m. When released, it lifts a length (h) of the string and then remains in equilibrium as in the figure. Now determine the value of (h). When deflated, the balloon has a mass of 0.25 kg. (Note: Only that part of th
At sunset, the Sun has an angular width for about 0.50 degrees. From the time the lower edge of the Sun just touches the horizon, about how long does it take the Sun, in minutes to disappear?
What is the total mass in kilograms of our solar system? And what is the equation for the speed of light? When solving a quadratic equation using the quadratic formula, is it possible for the b to the second power minus 4ac term inside the square root to be negative, thus forcing us to take the square root of a negative numb
Question: How can I calculate the solar power intercepted by the earth and the average temperature of the earth to radiate this power? e=1
The speed of light in vacuum is approximately 3 * 10^8 m/s. Calculate how long light takes to travel from the Earth to the Moon (distance 3.8 * 10^5km) and how long light takes to travel from the the sun to the Earth (distance 1.5 * 10^8km)?
I really need help on this one. Find the mass and radius of three of the nine planets in our solar system. I chose pluto, venus, mars. My masses must be expressed in kilograms and the radii expressed in meters. I am trying to calculate the gravitational acceleration on each of the three planets I selected. The masses must be m
Without using the value of G or the actual value of any masses, estimate the ratio of the mean density of the Earth to that of the Sun. The only facts you may use are those that a nonscientist might be aware of, the fact that the Moon's radius is three and one half times smaller than Earth's radius and the scaling implicit to Ke
1. How much potential energy does an object have that has a mss of 10 kg and is 4 meters off the ground on earth? 2. How much potential energy does an object have that has a mass of 10 kg and is 4 meters off the ground on the moon where gravity is 1.6(m/s^2)? 3. If the object falls half way to the ground so that its height is
Two geostationary communication satellites are placed in orbits whose radii are 4.23 x 10^7 m. The orbit is in the plane of the equator and the satellites have an angular separation of 2.00 degrees. Find the arc length that separates the satellites.

Show that escape speed is the square root of 2 times as large as the orbital speed of an object in orbit just above the earth's surface.
The International Space Station is in a nearly circular orbit at an altitude of 398.00 km above the surface of the earth. A maintenance crew is about to arrive on the space shuttle that is also in a circular in the same orbital plane as the ISS, but with an altitude of 398.10km. The crew has come to remove a faulty 125 m c
A spacecraft is to be launched from the surface of the earth so that it will escape from the SOLAR SYSTEM altogether. a) Find the speed relative to the center of the earth with which the spacecraft must be launched. Take into consideration the gravitational effects of both the earth and the sun, and include the effect of the
Very far from earth (at R=infinity), a spacecraft has run out of fuel and its kinetic energy is zero. If only the gravitational force of the earth were to act on it (i.e., neglect the forces from the sun and other solar system objects), the spacecraft would eventually crash into the earth. The mass of the earth is M_e and its ra
