Question Solved1 Answer A planet has a mass of 2.1x1024 kg and travels in a nearly circular orbit around a star as shown. When it is at location A, the velocity of the planet is ( 0, 0, –1.9×104 m/s. When it reaches location B, the planet's velocity is ( -1.9×104, 0, 0 m/s. We're looking down on the orbit from above, with +x to the right and +z down the page. PB B РА Sun (a) What is Ap, the change in the momentum of the planet between locations A and B? Ap = 3.99 · 1028 kg · m/s (b) On a copy of the diagram, draw two arrows representing the momentum of the planet at locations C and D, paying attention to both the length and direction of each arrow. What is the direction of the change in the momentum of the planet between locations C and D? h b f e j zero magnitude a C
