Need C please

Item 4 Part B At a certain instant, the earth, the moon, and a stationary 1430 kg spacecraft lie at the vertices of an equilateral triangle whose sides are 3.84 × 105 km! in length. 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. 0.607 Submit My Answers Give Up Correct Part 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?

Explanation / Answer

The minimum amount of work.

let it be W.

we have W + E_potential = 0

so W= -E_potential = -1430 x G x (m1+m2)/r = - 1.50 x 109 (J)
