Unformatted text preview: & F . d. Which of the components of the force & F || or & F , is responsible for changing the direction of the asteroids momentum? e. At the instant shown, is the magnitude of the asteroids momentum increasing, decreasing, or not changing? If you answered that the magnitude of the asteroids momentum is changing, which component(s) of the force is (are) responsible for the change? f. Calculate the gravitational force on the asteroid due to the Earth. Show all steps in your work, and express your answer as a three-component vector. g. What is the momentum of the asteroid 10 hours, or 3.6 x 10 4 seconds later? Show all steps in your work and express your answer as a three-component vector. You may assume that this is a relatively short period of time. h. What is the new position of the asteroid 10 hours later? Show all steps in your work and express your answer as a three-component vector....
