At a certain instant, the earth, the moon, and a stationary 1020 kg spacecraft lie at the vertices of an equilateral triangle whose sides are 3.84×105km3.84×105km in length.

(a) Find the magnitude of the net gravitational force exerted on the spacecraft by the earth and moon.

Express your answer to three significant figures.

(b) Find the direction of the net gravitational force exerted on the spacecraft by the earth and moon. State the direction as an angle measured from a line connecting the earth and the spacecraft.

Express your answer to three significant figures.

(c) What is the minimum amount of work that you would have to do to move the spacecraft to a point far from the earth and moon? You can ignore any gravitational effects due to the other planets or the sun.

Express your answer to three significant figures.

Stationary planets “A” and “B”, each with mass 1024 kg, are located 106 m away from each other in the horizontal direction (x). Space capsule “C” with a mass of 1000 kg starts at rest 106 m from both “A” and “B”, so the three objects form an equilateral triangle. Assume that “A” and “B” have a fixed position and cannot move, while “C” is able to move freely. What is the net gravitational force vector on “C” at time...
