Suppose we want a satellite to revolve around the Earth 9 times a day. What should the radius of its orbit be? (Neglect the presence of the moon.) 1.02 × 107 m 8.78 × 107 m 0.98 × 107 m 2.11 × 107 m
Q12-2 Gravitation 1. Find the speed of a satellite in a circular orbit around the Earth with a radius 2.71 times the mean radius of the Earth. (Radius of Earth = 6.37 x 10 km, mass of Earth = 5.98 x 1024 kg, -6.67 x 10" Nm /kg.) (in m/s) 2 V- 5.67 XII VA
A satellite in a circular orbit around the earth with a radius 1.015 times the mean radius of the earth is hit by an incoming meteorite. A large fragment (m = 89.0 kg) is ejected in the backwards direction so that it is stationary with respect to the earth and falls directly to the ground. Its speed just before it hits the ground is 359.0 m/s. Find the total work done by gravity on the satellite fragment. RE 6.37·103 km;...
Consider a satellite of mass m moving in a circular orbit around the Earth at a constant speed v and at an altitude h above the Earth's surface as illustrated in the figure. (a) Determine the speed of the satellite in terms of G, h, Re (the radius of the Earth), and Me (the mass of the Earth). (b) If the satellite is to be geosynchronous (that is, appearing to remain over a fixed position on the Earth), how fast...
4. A 1000-kg satellite in circular orbit around the Earth is moving at a speed of 7 x 10 m/s. How much work must be done to "raise" the satellite to a higher circular orbit doubling its height above the surface of the Earth?
A satellite of mass m (where m ≪ Me) is initially in a circular orbit around the Earth at a height of 410 km above the Earth’s equator. Its operators would like to move it into a geosynchronous orbit using a Hohmann transfer orbit. Assume a spherical Earth with radius 6371 km. (a) Sketch the satellite’s Hohmann transfer orbit. (b) Find the satellite’s initial (circular) orbital speed according to an inertial observer. (c) Find the maximum height of the satellite...

Many communication satellites are placed in a circular orbit around the Earth at a radius where the period (the time to go around the Earth once) is 24 hours. If the satellite is above some point on the equator, it stays above that point as the Earth rotates, so that as viewed from the rotating Earth the satellite appears to be motionless. That is why you see dish antennas pointing at a "fixed" point in space. (a) Calculate the radius...
A spy satellite is in circular orbit around Earth. It makes one revolution in 7.20 h. Mass of Earth is 5.974 × 1024 kg, radius of Earth is 6371 km and Gravitational constant G is = 6.674 × 10−11 N·m2/kg2. How high above Earth’s surface is the satellite?
Problem 8 Scientists want to place a 3500 kg satellite in orbit around Mars. They plan to have the satellite orbit a distance equal to 1.5 times the radius af Mars above the surface of the planet. Here is some information that will help solve this prablem: mma: 6.4191 x 1023kg mas 3.397 x 10%m G-6.67428 x 10 11 Nrn2/kg2 What is the force of attraction bet ween Mars and the satellite?
