A future news release might report that a new planet has been found around a star very similar to our Sun. The system contains other planets as well like our solar system. This newly discovered planet is claimed to have a mass 40 times that of Earth and is located nearly 25 AU from the star it orbits. Which of the following would be a reasonable prediction about this planet, assuming it formed
like our solar system? I. The planet will probably have a mean density of around 5 g/cm3. II. The planet will probably have a radius of around five to ten times greater than Earth's. III. The planet will probably have several satellites. IV. The planet will probably have a composition that is mostly hydrogen and helium. a. I & IV b. I, II, & III c. II, III, & IV d. I, II, & IV e. I, II, III, & IV

The kinetic energy of the rock is smaller than in the first case, but the momenta of both are the same. c. The kinetic energies of the rocks are the same in both cases. d. The kinetic energy of the rock is 1/9 its previous value.
