PHYS 2 Study Guide - Midterm Guide: Earth Radius, Orbital Period, Angular Acceleration
Document Summary
Problem 1 (46 points) a planet of mass m is orbited by two identical moons, each of mass m/3. The two moons both follow the same orbit or radius r around the planet, and are always on opposite sides of the planet. Each moon experiences a gravitational force from the planet and a gravitational force from the other moon. (a) find the magnitude of the net gravitational force exerted on either moon by the planet and the other moon. You will lose points if you substitute a numerical value for g. ) for full credit, show your work, simplify your answer, and draw a box around your final answer. (continued on next page) Problem 1 (continued) (b) find the orbital period of either moon. Your answer should involve no quantities other than m, g, and r. (it may or may not involve all of these quantities. You will lose points if you substitute a numerical value for.
