Question:
1) A rocket is initially in a circular orbit of radius about the Earth. At point the rocket fires its thrusters to decrease its speed. Which of the dashed elliptical orbits will the rocket take?
A) The smaller elliptical orbit (#1)
B) The larger elliptical orbit (#2)
C) It will stay in the circular orbit
2) A rocket is initially in a circular orbit of radius about the Earth. At point, the rocket fires its thrusters to increase its speed. How will the rocket’s total energy change?
A) It will increase
B) It will decrease
C) It will remain the same
