A space station out beyond the solar system is rotating with constant angular velocity. A spaceship heading into the station along a diameter of the station, uses its rockets to brake, and then docks inside the station at its center. When the spaceship docks, the angular momentum of the system consisting of the station and ship
 a. is less than the original angular momentum of the station.
  b. is the same as the original angular momentum of the station.
  c. is greater than the original angular momentum of the station.
  d. is less than the original angular momentum of the station, but the angular velocity increases.
  e. is greater than the original angular momentum of the station, but the angular velocity decreases.

Question 2

A hockey puck traveling at speed v on essentially frictionless ice collides with one end of a straight stick lying flat on the ice and sticks to that end. In this collision
 a. momentum is conserved. b. angular momentum is conserved. c. energy is conserved. d. all of the above are conserved. e. only momentum and angular momentum are conserved.
