At a particular instant the magnitude of the momentum of a planet is 2.25 times 1029 kg m/s, and the force exerted on It by the star It is orbiting is 9.2 times 1022 N. The angle between the planet's momentum and the gravitational force exerted by the star is 129degree. What is the parallel component of the force on the planet by the star? What will the magnitude of the planet's momentum be after 8 h? (Enter your answer to at least four significant figures.)
