A rocket with mass 4.00 times 10^3 kg is in a circular orbit of radius 7.10 times 10^8 m arcund the earth, The rocket's engines fire for a period of time to increase that radius to 8 80 times 10^6 m, with the orbit again circular, What is the change in the rocket's kinetic energy? Does the kinetic energy increase or decrease? Express your answer with the appropriate units. Enter positive value if the kinetic energy increases and negative value...
A rocket with mass 5.00×103 kg is in a circular orbit of radius 7.30×106 m around the earth. The rocket's engines fire for a period of time to increase that radius to 8.70×106 m , with the orbit again circular. What is the change in the rocket's kinetic energy? Does the kinetic energy increase or decrease?
A satellite is in a circular Earth orbit of radius r. The area A enclosed by the orbit depends on r2 because A = ?r2. Determine how the following properties of the satellite depend on r. In each case, give the power of r, i.e., if the dependence goes as rn, give n. If there is no dependence, then n = 0. (a) period, (b) kinetic energy, (c) angular momentum, and (d) speed.
Consider a satellite (mass = 46 kg) in a circular orbit about Earth. Calculate the following properties of the satellite given a radius r of its orbit of 1.21
An 825 kg space vehicle is circling Earth in a circular orbit with a radius of 10,300 km. Its orbit is to be changed to a larger circle with a radius of 17,400 km. Howmuch energy is required to accomplish this?
A satellite of mass m is in a circular orbit of radius r about a planet of mass M. The period of the satellite's orbit is T. A second satellite of mass 2m is in a circular orbit of radius 2r around the same planet. The period of orbit for the second satellite is 2T 8T O2T OT O 4T
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 spacecraft of mass m = 1900 kg is moving on a circular orbit about the earth at a constant speed v = 5.12 km/s. [Given: Mass of the earth M = 5.98 times 10^24 kg, radius of the earth R = 6.37 times10^6 m, gravitational constant G = 6.67 times 10^-11 N.m^2/kg^2.] a. Determine the radius r of the circular orbit. b. What is the period T of the orbit? c. The satellite, by firing its engines, moves to...
A satellite is in a circular Earth orbit of radius r. The area A enclosed by the orbit depends on r2 because A = πr2. Determine how the following properties of the satellite depend on r. In each case, give the power of r, i.e., if the dependence goes as rn, give n. If there is no dependence, then n = 0. (a) period, (b) kinetic energy, (c) angular momentum, and (d) speed.
