Question
Space debris left from old satellites and their
launchers is becoming a 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°. What is the
velocity of the rivet relative to the satellite just
before striking it? (c) If its mass is 0.500 g, and it
comes to rest inside the satellite, how much energy
in joules is generated by the collision? (Assume the
satellite's velocity does not change appreciably,
because its mass is much greater than the rivet's.)
