Question 10 One way to attack a satellite in Earth orbit is to launch a swarm of pellets in the same orbit as the satellite but in the opposite direction. Suppose a satellite in a circular orbit 670 km above Earth's surface collides with a pellet having mass 3.7 g. (a) What is the kinetic energy of the pellet in the reference frame of the satellite just before the collision? (b) What is the ratio of this kinetic energy to...

2. Consider a system consisting of the Sun, Earth, and a satellite in a circular orbit about the Earth. (a) Plot the gravitational acceleration of the satellite due to Earth's gravity as a function of the altitude of the satellite as measured from the surface of the Earth. Scale your plot so that the altitude goes from 0 km to 104 km. (b) Assume that the satellite instantaneously lies on the line between the Earth and the Sun. Make two...

A geostationary orbit is one in which a satellite orbits the Earth (in a circular orbit) in the same time as it takes the Earth to make one full rotation with respect to the stars. a) Given the mass of the Earth, calculate the distance of a geostationary satellite from the center of the Earth. b) If you were standing on the equator with the geostationary satellite at your zenith, how long would it take to receive a radio signal?...
