The diagram below is a graph of the energy of a system of a planet interacting with a star. The gravitational potential energy U, is shown as the thick curve, and plotted along the vertical axis are various values of K+Ug. r, from star to planet Suppose that K+U, of the system is A. Which of the following statements are true? O When the separation between the two bodies is r2, the kinetic energy of the system is (B - C). O The planet will escape. O When the separation between the two bodies is r2, the kinetic energy of the system is (A - B). O The kinetic energy of the system is greater when the distance between the star and planet is r than when the distance between the two bodies is r2. O The potential energy of the system decreases as the planet moves from r, to r2. O The system is a bound system; the can never escape. Suppose instead that K+U, of the system is B. Which of the following statements are true? O This is not a bound system; the planet can escape. O When the separation between the planet and star is r2, the potential energy of the system is zero. O When the separation between the planet and star is r2, the kinetic energy of the system is zero. O The planet and star cannot get farther apart than r2.
