Space debris from outdated satellites and their launchers poses an increasing hazard to other satellites.
a. Calculate the speed of a satellite in an orbit 900 km above Earth's surface.
b. Suppose a loose rivet is in an orbit of the same radius that intersects the satellite's orbit at an angle of 90 degrees. What is the velocity of the rivet relative to the satellite just before striking it?
c. If the mass of the rivet is 0.500 g and it comes to rest inside the satellite after the collision, determine the energy, in joules, generated by the collision. (Assume the satellite's velocity remains relatively unchanged due to its much greater mass compared to the rivet.)
