Aspace ship is landing on the moon, and another is landing on earth. both space ships have a mass of 100 kilograms, and both have a velocity of 100 m/s. the earth is pulling on the first spaceship so that its acceleration rate is 10 m/s², while the moon is pulling on the second so that the acceleration is 1 m/s². both ships need to stop in 10 seconds, how much more force is required to stop the first spaceship than the second?
