A 3410-kg spacecraft is in a circular orbit 2250 km above the surface of Mars.
How much work must the spacecraft engines perform to move the spacecraft to a circular orbit that is 4360 km above the surface?Express your answer to three significant figures.
Homework Answers
Work, W = (GMm/2)[-1/(R + hf) + 1/(R + hi)]
W = (6.67 x 10^-11)(6.39 x 10^23 x 3410/2)[-1/(3.39 x 10^6 + 4360000) + 1/(3.39 x 10^6 +2250000)]
W = 3.51 x 10^9 J

A 3390-kg spacecraft is in a circular orbit 1990 km above the surface of Mars. How much work must the spacecraft engines perform to move the spacecraft to a circular orbit that is 3990 km above the surface? Express your answer to three significant figures. Please find deltaE The answer is not 6.336*10^9, 0.407 *10^10 , 7.05*10^9 , 1.56*10^10 It is something different, all of the above are wrong.

80.A spacecraft is approaching Mars after a long trip from the Earth. Its velocity is such that it is traveling along a parabolic trajectory under the influence of the gravitational force from Mars. The distance of closest approach will be 300 km above the Martian surface. At this point of closest approach, the engines will be fired to slow down the spacecraft and place it in a circular orbit 300 km above the surface. (a) By what percentage must the...
